Major redesigns of its [[graphical user interface]] occurred on versions 4.0 in March 2011, 29.0 "Australis" in April 2014, 57.0 "Quantum" in November 2017, and 89.0 "Proton" in June 2021.
In 2016, Mozilla announced a project known as [[Quantum (Mozilla)|Quantum]], which sought to improve Firefox's Gecko engine and other components to improve the browser's performance, modernize its architecture, and transition the browser to a [[Process isolation|multi-process]] model. These improvements came in the wake of decreasing market share to [[Google Chrome]], as well as concerns that its performance was lapsing in comparison. Despite its improvements, these changes required existing [[Add-on (Mozilla)|add-ons]] for Firefox to be made incompatible with newer versions, in favor of a new [[Browser extension|extension]] system that is designed to be similar to Chrome and other recent browsers. Firefox 57, which was released in November 2017, was the first version to contain enhancements from Quantum, and has thus been named ''Firefox Quantum''. A Mozilla executive stated that Quantum was the "biggest update" to the browser since version 1.0.<ref name="cnet57">{{cite news |url=https://www.cnet.com/special-reports/mozilla-firefox-fights-back-against-google-chrome/ |title=Inside Mozilla: Firefox fights back |last=Shankland |first=Stephen |date=August 4, 2017 |work=[[CNET]] |access-date=October 9, 2017 |publisher=[[CBS Interactive]] |archive-url=https://web.archive.org/web/20170803165258/https://www.cnet.com/special-reports/mozilla-firefox-fights-back-against-google-chrome/ |archive-date=August 3, 2017 |url-status=live }}</ref><ref>{{cite news |url=https://www.zdnet.com/article/why-you-should-root-for-mozillas-firefox-57-in-the-browser-wars/ |title=Why you should root for Mozilla's Firefox 57 in the browser wars |last=Dignan |first=Larry |date=August 6, 2017 |publisher=[[ZDNet]] |access-date=October 9, 2017 |archive-url=https://web.archive.org/web/20171211021103/https://www.zdnet.com/article/why-you-should-root-for-mozillas-firefox-57-in-the-browser-wars/ |archive-date=December 11, 2017 |url-status=live}}</ref><ref>{{Cite news |url=https://www.computerworld.com/article/3237054/internet/mozilla-seeks-return-to-glory-with-release-of-firefox-quantum.html |title=Mozilla seeks return to glory with release of Firefox Quantum |last=Keizer |first=Gregg |date=November 14, 2017 |work=[[Computerworld]] |access-date=December 11, 2017 |archive-url=https://web.archive.org/web/20171223114527/https://www.computerworld.com/article/3237054/internet/mozilla-seeks-return-to-glory-with-release-of-firefox-quantum.html |archive-date=December 23, 2017 |url-status=live |publisher=[[International Data Group]]}}</ref> Unresponsive and crashing pages only affect other pages loaded within the same process.

=== Guest session ===
Firefox for Android was equipped with a ''guest session'' feature, introduced in 2013, which, when initiated, would memorize ordinary browsing data such as tabs, cookies, and history, but for the duration of the guest session. The guest session data would be kept even when restarting the browser or device, while deleted only upon a manual exit. The feature was removed, for which Mozilla claims to "''streamline the experience''".<ref>{{cite web |title=Share Your Firefox with Friends & Family While Keeping Your Web Information Private with Guest Browsing |url=https://blog.mozilla.org/blog/2013/10/29/share-your-firefox-with-friends-family-while-keeping-your-web-information-private-with-guest-browsing |website=The Mozilla Blog |date=October 29, 2013 |access-date=January 27, 2021 |archive-date=January 27, 2021 |archive-url=https://web.archive.org/web/20210127033206/https://blog.mozilla.org/blog/2013/10/29/share-your-firefox-with-friends-family-while-keeping-your-web-information-private-with-guest-browsing/ |url-status=live }}</ref><ref>{{Cite web|url=https://support.mozilla.org/en-US/kb/share-your-android-device-firefox-guest-session|title=Share your Android device with a Firefox Guest Session | Firefox for Android (ESR) Help|website=support.mozilla.org|access-date=January 27, 2021|archive-date=January 27, 2021|archive-url=https://web.archive.org/web/20210127031057/https://support.mozilla.org/en-US/kb/share-your-android-device-firefox-guest-session|url-status=live}}</ref>

Since version 38 on [[Windows Vista]] and newer, Firefox supports the playback of video content protected by HTML5 [[Encrypted Media Extensions]] (EME). For security and privacy reasons, EME is implemented within a wrapper of open-source code that allows execution of a [[proprietary software|proprietary]] [[digital rights management|DRM]] module by [[Adobe Systems]]—Adobe Primetime Content Decryption Module (CDM). CDM runs within a "[[sandbox (computer security)|sandbox]]" environment to limit its access to the system and provide it a randomized device ID to prevent services from [[Device fingerprint|uniquely identifying the device]] for tracking purposes. The DRM module, once it has been downloaded, is enabled, and disabled in the same manner as other [[Plug-in (computing)|plug-ins]].

In February 2013, plans were announced for Firefox 22 to disable [[third-party cookie]]s by default. However, the introduction of the feature was then delayed so Mozilla developers could "collect and analyze data on the effect of blocking some third-party cookies."

Version 23, released in August 2013, followed the lead of its competitors by blocking [[HTML element#Frames|iframe]], stylesheet, and script resources served from non-HTTPS servers embedded on HTTPS pages by default. Additionally, [[JavaScript]] could also no longer be disabled through Firefox's preferences, and JavaScript was automatically re-enabled for users who upgraded to 23 or higher with it disabled. The change was made due to its use across the majority of websites, the potential repercussions on inexperienced users who are unaware of its impact, along with the availability of extensions such as [[NoScript]], which can disable JavaScript in a more controlled fashion. The following release added the ability to disable JavaScript through the developer tools for testing purposes.<ref name="ff23-relnotes">{{cite web|url=https://www.mozilla.org/en-US/firefox/23.0/releasenotes/|title=Firefox 23 Release Notes|date=August 6, 2013|publisher=[[Mozilla.org]]|access-date=March 14, 2014|archive-url=https://web.archive.org/web/20140328214014/http://www.mozilla.org/en-US/firefox/23.0/releasenotes/|archive-date=March 28, 2014|url-status=live}}</ref><ref>{{cite news|url=https://arstechnica.com/information-technology/2013/08/firefox-23-lands-with-a-new-logo-and-mixed-content-blocking/|title=Firefox 23 lands with a new logo and mixed content blocking|last=Bright|first=Peter|date=August 6, 2013|work=[[Ars Technica]]|access-date=March 14, 2014|archive-url=https://web.archive.org/web/20140218022903/http://arstechnica.com/information-technology/2013/08/firefox-23-lands-with-a-new-logo-and-mixed-content-blocking/|archive-date=February 18, 2014|url-status=live}}</ref><ref>{{cite news|url=http://www.extremetech.com/computing/163291-firefox-23-finally-kills-the-blink-tag-removes-ability-to-turn-off-javascript-introduces-new-logo|title=Firefox 23 finally kills the blink tag, removes ability to turn off JavaScript, introduces new logo|last=Anthony|first=Sebastian|date=August 7, 2013|newspaper=ExtremeTech|access-date=March 14, 2014|archive-url=https://web.archive.org/web/20140329071544/http://www.extremetech.com/computing/163291-firefox-23-finally-kills-the-blink-tag-removes-ability-to-turn-off-javascript-introduces-new-logo|archive-date=March 29, 2014|url-status=live}}</ref>

Beginning with Firefox 48, all extensions must be signed by Mozilla to be used in release and beta versions of Firefox.

There has been some controversy over the Mozilla Foundation's intentions in stopping certain open-source distributions from using the "Firefox" trademark.<ref name=LWNtrademark/> Open-source browsers "enable greater choice and innovation in the market rather than aiming for mass-market domination."<ref name=":0"/> Mozilla Foundation Chairperson [[Mitchell Baker]] explained in an interview in 2007 that distributions could freely use the Firefox trademark if they did not modify source code, and that the Mozilla Foundation's only concern was with users getting a consistent experience when they used "Firefox".<ref>{{cite news |first=Dan |last=Warne |title=The stoush over Linux distributions using the Firefox trademark |work=APC Magazine |publisher=ACP Magazines Ltd |date=May 7, 2007 |url=http://apcmag.com/the_stoush_over_linux_distributions_using_the_firefox_trademark.htm |access-date=January 18, 2008 |archive-url=https://web.archive.org/web/20110817064956/http://apcmag.com/the_stoush_over_linux_distributions_using_the_firefox_trademark.htm |archive-date=August 17, 2011 |url-status=live }}</ref>
To allow distributions of the code ''without'' using the official branding, the Firefox [[build automation|build system]] contains a "branding switch". This switch, often used for alphas ("Auroras") of future Firefox versions, allows the code to be compiled without the official logo and name and can allow a derivative work unencumbered by restrictions on the Firefox trademark to be produced. In the unbranded build, the trademarked logo and name are replaced with a freely distributable generic globe logo and the name of the release series from which the modified version was derived.{{Citation needed|date=September 2020}}
Distributing modified versions of Firefox under the "Firefox" name required explicit approval from Mozilla for the changes made to the underlying code, and required the use of ''all'' of the official branding. For example, it was not permissible to use the name "Firefox" without also using the official logo. When the [[Debian]] project decided to stop using the official Firefox logo in 2006 (because Mozilla's copyright restrictions at the time were incompatible with [[Debian Free Software Guidelines|Debian's guidelines]]), they were told by a representative of the Mozilla Foundation that this was not acceptable and was asked either to comply with the published trademark guidelines or cease using the "Firefox" name in their distribution.<ref>{{cite web|url=https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=354622|title=Debian Bug report logs – #354622: Uses Mozilla Firefox trademark without permission|publisher=Debian|access-date=January 30, 2007|archive-url=https://web.archive.org/web/20130206164312/http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=354622|archive-date=February 6, 2013|url-status=live}}</ref> <!-- is this important enough to include in the context of this article? - Some Debian developers had misunderstood previous communication to be an agreement that allowed them to do this, but Mozilla disputed this assertion. --> Debian switched to branding their modified version of Firefox "[[Mozilla software rebranded by Debian|Iceweasel]]" (but in 2016 switched back to Firefox), along with other Mozilla software.

=== Branding and visual identity ===
The Firefox icon is a trademark used to designate the official Mozilla build of the Firefox software and builds of official distribution partners.<ref>[https://www.mozilla.org/foundation/trademarks/distribution-policy.html Mozilla Trademark Policy for Distribution Partners] {{Webarchive|url=https://web.archive.org/web/20130402194222/https://www.mozilla.org/foundation/trademarks/distribution-policy.html |date=April 2, 2013 }} Version 0.9 (DRAFT). Retrieved November 2, 2006.</ref> For this reason, software distributors who distribute modified versions of Firefox do not use the icon.{{Citation needed|date=September 2020}}
Early Firebird and Phoenix releases of Firefox were considered to have reasonable visual designs but fell short when compared to many other professional software packages. In October 2003, professional interface designer Steven Garrity authored an article covering everything he considered to be wrong with Mozilla's visual identity.<ref name="branding-mozilla">{{cite web|last=Garrity|first=Steven|title=Branding Mozilla: Towards Mozilla 2.0|url=http://www.actsofvolition.com/files/mozillabranding/|access-date=February 8, 2009|date=October 23, 2003|archive-url=https://web.archive.org/web/20090115202336/http://www.actsofvolition.com/files/mozillabranding/|archive-date=January 15, 2009|url-status=live}}</ref>
Shortly afterwards, the Mozilla Foundation invited Garrity to head up the new visual identity team. The release of Firefox 0.8 in February 2004 saw the introduction of the new branding efforts. Included were new icon designs by silverorange, a group of web developers with a long-standing relationship with Mozilla. The final renderings are by [[Jon Hicks (designer)|Jon Hicks]], who had worked on [[Camino (web browser)|Camino]].<ref name="branding-mozilla-followup">{{cite web|url=http://www.actsofvolition.com/archive/2004/february/brandingmozilla|title=Branding Mozilla: Towards Firefox 1.0|last=Garrity|first=Steven|date=February 9, 2004|access-date=February 8, 2009|archive-url=https://web.archive.org/web/20090205043028/http://www.actsofvolition.com/archive/2004/february/brandingmozilla|archive-date=February 5, 2009|url-status=live}}</ref><ref name="branding-firefox">{{cite web|url=https://www.hicksdesign.co.uk/journal/branding-firefox|title=Branding Firefox|last=Hicks|first=Jon|date=February 9, 2004|publisher=Hicksdesign|access-date=February 8, 2009|archive-url=https://web.archive.org/web/20090208065605/http://hicksdesign.co.uk/journal/branding-firefox|archive-date=February 8, 2009|url-status=live}}</ref> The logo was later revised and updated, fixing several flaws found when it was enlarged.<ref name="spot-the-difference">{{cite web|url=https://www.hicksdesign.co.uk/journal/spot-the-difference/|title=Spot the Difference|last=Hicks|first=Jon|date=December 17, 2004|publisher=Hicksdesign|access-date=February 8, 2009|archive-url=https://web.archive.org/web/20090205061152/http://www.hicksdesign.co.uk/journal/spot-the-difference/|archive-date=February 5, 2009|url-status=live}}</ref> The animal shown in the logo is a stylized fox, although "firefox" is usually a common name for the [[red panda]].

In June 2019, Mozilla unveiled a revised Firefox logo, which was officially implemented on version 70. The new logo is part of an effort to build a brand system around Firefox and its complementary apps and services, which are now being promoted as a suite under the Firefox brand.

In January 2010, Lifehacker compared the performance of Firefox 3.5, Firefox 3.6, Google Chrome 4 (stable and Dev versions), Safari 4, and Opera (10.1 stable and 10.5 pre-alpha versions). Lifehacker timed how long browsers took to start and reach a page (both right after boot-up and after running at least once already), timed how long browsers took to load nine tabs at once, tested JavaScript speeds using Mozilla's Dromaeo online suite (which implements Apple's [[Browser speed test#Apple benchmarks|SunSpider]] and Google's V8 tests) and measured memory usage using Windows 7's process manager. They concluded that Firefox 3.5 and 3.6 were the fifth- and sixth-fastest browsers, respectively, on startup, 3.5 was third- and 3.6 was sixth-fastest to load nine tabs at once, 3.5 was sixth- and 3.6 was fifth-fastest on the JavaScript tests. They also concluded that Firefox 3.6 was the most efficient with memory usage followed by Firefox 3.5.<ref>{{cite news|url=https://lifehacker.com/5457242/browser-speed-tests-firefox-36-chrome-4-opera-105-and-extensions|title=Browser Speed Tests: Firefox 3.6, Chrome 4, Opera 10.5, and Extensions|last=Purdy|first=Kevin|date=January 26, 2010|access-date=May 4, 2010|publisher=Lifehacker|archive-url=https://web.archive.org/web/20100504143754/http://lifehacker.com/5457242/browser-speed-tests-firefox-36-chrome-4-opera-105-and-extensions|archive-date=May 4, 2010|url-status=live}}</ref>
In February 2012, ''[[Tom's Hardware]]'' performance tested Chrome 17, Firefox 10, [[Internet Explorer 9]], Opera 11.61, and Safari 5.1.2 on Windows 7. ''Tom's Hardware'' summarized their tests into four categories: Performance, Efficiency, Reliability, and Conformance. In the performance category they tested [[HTML5]], [[Java (software platform)|Java]], [[JavaScript]], [[Document Object Model|DOM]], [[CSS 3]], [[Adobe Flash|Flash]], [[Silverlight]], and [[WebGL]] ([[WebGL 2]] is current as of version 51; and Java and Silverlight stop working as of version 52)—they also tested startup time and page load time. The performance tests showed that Firefox was either "acceptable" or "strong" in most categories, winning three categories (HTML5, HTML5 [[hardware acceleration]], and Java) only finishing "weak" in CSS performance. In the efficiency tests, ''Tom's Hardware'' tested memory usage and management. In this category, it determined that Firefox was only "acceptable" at performing light memory usage, while it was "strong" at performing heavy memory usage. In the reliability category, Firefox performed a "strong" amount of proper page loads. In the final category, conformance, it was determined that Firefox had "strong" conformance for JavaScript and HTML5. In conclusion, ''Tom's Hardware'' determined that Firefox was the best browser for Windows 7 OS, but that it only narrowly beat Google Chrome.<ref>{{cite web|url=https://www.tomshardware.com/reviews/chrome-17-firefox-10-ubuntu,3129-17.html|title=Benchmark Analysis: Windows 7 and Ubuntu 11.10|last=Overa|first=Adam|date=February 21, 2012|publisher=Tom's Hardware|access-date=April 8, 2012|archive-date=September 13, 2012|archive-url=https://archive.today/20120913011235/http://www.tomshardware.com/reviews/chrome-17-firefox-10-ubuntu,3129-17.html|url-status=live}}</ref>
In June 2013, ''Tom's Hardware'' again performance tested Firefox 22, Chrome 27, Opera 12, and [[Internet Explorer 10]]. They found that Firefox slightly edged out the other browsers in their "performance" index, which examined wait times, JavaScript execution speed, HTML5/CSS3 rendering, and hardware acceleration performance. Firefox also scored the highest on the "non-performance" index, which measured memory efficiency, reliability, security, and standards conformance, finishing ahead of Chrome, the runner-up. ''Tom's Hardware'' concluded by declaring Firefox the "sound" winner of the performance benchmarks.<ref name="Overa13">{{cite news|url=https://www.tomshardware.com/reviews/chrome-27-firefox-21-opera-next,3534-12.html|title=Chrome 27, Firefox 22, IE10, And Opera Next, Benchmarked|last=Overa|first=Adam|date=June 30, 2013|newspaper=Tom's Hardware|access-date=May 2, 2014|archive-date=July 3, 2013|archive-url=https://archive.today/20130703091630/http://www.tomshardware.com/reviews/chrome-27-firefox-21-opera-next,3534-12.html|url-status=live}}</ref>

In benchmark testing in early 2015 on a "high-end" Windows machine, comparing [[Microsoft Edge]], Internet Explorer, Firefox, Chrome, and Opera, Firefox achieved the highest score on three of the seven tests. Four different JavaScript performance tests gave conflicting results. Firefox surpassed all other browsers on the [[Browser speed test|Peacekeeper benchmark]] but was behind the Microsoft products when tested with SunSpider. Measured with Mozilla's Kraken, it came second place to Chrome, while on Google's [[Browser speed test#Octane|Octane]] challenge it took third behind Chrome and Opera. Firefox took the lead with WebXPRT, which runs several typical HTML5 and JavaScript tasks. Firefox, Chrome, and Opera all achieved the highest possible score on the Oort Online test, measuring WebGL rendering speed (WebGL 2 is now current). In terms of HTML5 compatibility testing, Firefox was ranked in the middle of the group.<ref name="TekRevue-2015-04-01">{{cite web|url=https://www.tekrevue.com/spartan-benchmarks-ie-chrome-firefox-opera/|title=Spartan Benchmarks: Spartan vs. IE, Chrome, Firefox, and Opera|last=Tanous|first=Jim|date=April 1, 2015|website=TekRevue|access-date=January 10, 2016|archive-url=https://web.archive.org/web/20151226174659/http://www.tekrevue.com/spartan-benchmarks-ie-chrome-firefox-opera/|archive-date=December 26, 2015|url-status=live}}</ref>
A similar set of benchmark tests in 2016 showed Firefox's JavaScript performance on Kraken and the newer [[Browser speed test#JetStream|Jetstream]] tests trailing slightly behind all other tested browsers except Internet Explorer (IE), which performed relatively poorly.

Major redesigns of its [[graphical user interface]] occurred on versions 4.0 in March 2011, 29.0 "Australis" in April 2014, 57.0 "Quantum" in November 2017, and 89.0 "Proton" in June 2021.
In 2016, Mozilla announced a project known as [[Quantum (Mozilla)|Quantum]], which sought to improve Firefox's Gecko engine and other components to improve the browser's performance, modernize its architecture, and transition the browser to a [[Process isolation|multi-process]] model. These improvements came in the wake of decreasing market share to [[Google Chrome]], as well as concerns that its performance was lapsing in comparison. Despite its improvements, these changes required existing [[Add-on (Mozilla)|add-ons]] for Firefox to be made incompatible with newer versions, in favor of a new [[Browser extension|extension]] system that is designed to be similar to Chrome and other recent browsers. Firefox 57, which was released in November 2017, was the first version to contain enhancements from Quantum, and has thus been named ''Firefox Quantum''. A Mozilla executive stated that Quantum was the "biggest update" to the browser since version 1.0.<ref name="cnet57">{{cite news |url=https://www.cnet.com/special-reports/mozilla-firefox-fights-back-against-google-chrome/ |title=Inside Mozilla: Firefox fights back |last=Shankland |first=Stephen |date=August 4, 2017 |work=[[CNET]] |access-date=October 9, 2017 |publisher=[[CBS Interactive]] |archive-url=https://web.archive.org/web/20170803165258/https://www.cnet.com/special-reports/mozilla-firefox-fights-back-against-google-chrome/ |archive-date=August 3, 2017 |url-status=live }}</ref><ref>{{cite news |url=https://www.zdnet.com/article/why-you-should-root-for-mozillas-firefox-57-in-the-browser-wars/ |title=Why you should root for Mozilla's Firefox 57 in the browser wars |last=Dignan |first=Larry |date=August 6, 2017 |publisher=[[ZDNet]] |access-date=October 9, 2017 |archive-url=https://web.archive.org/web/20171211021103/https://www.zdnet.com/article/why-you-should-root-for-mozillas-firefox-57-in-the-browser-wars/ |archive-date=December 11, 2017 |url-status=live}}</ref><ref>{{Cite news |url=https://www.computerworld.com/article/3237054/internet/mozilla-seeks-return-to-glory-with-release-of-firefox-quantum.html |title=Mozilla seeks return to glory with release of Firefox Quantum |last=Keizer |first=Gregg |date=November 14, 2017 |work=[[Computerworld]] |access-date=December 11, 2017 |archive-url=https://web.archive.org/web/20171223114527/https://www.computerworld.com/article/3237054/internet/mozilla-seeks-return-to-glory-with-release-of-firefox-quantum.html |archive-date=December 23, 2017 |url-status=live |publisher=[[International Data Group]]}}</ref> Unresponsive and crashing pages only affect other pages loaded within the same process.

=== Guest session ===
Firefox for Android was equipped with a ''guest session'' feature, introduced in 2013, which, when initiated, would memorize ordinary browsing data such as tabs, cookies, and history, but for the duration of the guest session. The guest session data would be kept even when restarting the browser or device, while deleted only upon a manual exit. The feature was removed, for which Mozilla claims to "''streamline the experience''".<ref>{{cite web |title=Share Your Firefox with Friends & Family While Keeping Your Web Information Private with Guest Browsing |url=https://blog.mozilla.org/blog/2013/10/29/share-your-firefox-with-friends-family-while-keeping-your-web-information-private-with-guest-browsing |website=The Mozilla Blog |date=October 29, 2013 |access-date=January 27, 2021 |archive-date=January 27, 2021 |archive-url=https://web.archive.org/web/20210127033206/https://blog.mozilla.org/blog/2013/10/29/share-your-firefox-with-friends-family-while-keeping-your-web-information-private-with-guest-browsing/ |url-status=live }}</ref><ref>{{Cite web|url=https://support.mozilla.org/en-US/kb/share-your-android-device-firefox-guest-session|title=Share your Android device with a Firefox Guest Session | Firefox for Android (ESR) Help|website=support.mozilla.org|access-date=January 27, 2021|archive-date=January 27, 2021|archive-url=https://web.archive.org/web/20210127031057/https://support.mozilla.org/en-US/kb/share-your-android-device-firefox-guest-session|url-status=live}}</ref>

Since version 38 on [[Windows Vista]] and newer, Firefox supports the playback of video content protected by HTML5 [[Encrypted Media Extensions]] (EME). For security and privacy reasons, EME is implemented within a wrapper of open-source code that allows execution of a [[proprietary software|proprietary]] [[digital rights management|DRM]] module by [[Adobe Systems]]—Adobe Primetime Content Decryption Module (CDM). CDM runs within a "[[sandbox (computer security)|sandbox]]" environment to limit its access to the system and provide it a randomized device ID to prevent services from [[Device fingerprint|uniquely identifying the device]] for tracking purposes. The DRM module, once it has been downloaded, is enabled, and disabled in the same manner as other [[Plug-in (computing)|plug-ins]].

In February 2013, plans were announced for Firefox 22 to disable [[third-party cookie]]s by default. However, the introduction of the feature was then delayed so Mozilla developers could "collect and analyze data on the effect of blocking some third-party cookies."

Version 23, released in August 2013, followed the lead of its competitors by blocking [[HTML element#Frames|iframe]], stylesheet, and script resources served from non-HTTPS servers embedded on HTTPS pages by default. Additionally, [[JavaScript]] could also no longer be disabled through Firefox's preferences, and JavaScript was automatically re-enabled for users who upgraded to 23 or higher with it disabled. The change was made due to its use across the majority of websites, the potential repercussions on inexperienced users who are unaware of its impact, along with the availability of extensions such as [[NoScript]], which can disable JavaScript in a more controlled fashion. The following release added the ability to disable JavaScript through the developer tools for testing purposes.<ref name="ff23-relnotes">{{cite web|url=https://www.mozilla.org/en-US/firefox/23.0/releasenotes/|title=Firefox 23 Release Notes|date=August 6, 2013|publisher=[[Mozilla.org]]|access-date=March 14, 2014|archive-url=https://web.archive.org/web/20140328214014/http://www.mozilla.org/en-US/firefox/23.0/releasenotes/|archive-date=March 28, 2014|url-status=live}}</ref><ref>{{cite news|url=https://arstechnica.com/information-technology/2013/08/firefox-23-lands-with-a-new-logo-and-mixed-content-blocking/|title=Firefox 23 lands with a new logo and mixed content blocking|last=Bright|first=Peter|date=August 6, 2013|work=[[Ars Technica]]|access-date=March 14, 2014|archive-url=https://web.archive.org/web/20140218022903/http://arstechnica.com/information-technology/2013/08/firefox-23-lands-with-a-new-logo-and-mixed-content-blocking/|archive-date=February 18, 2014|url-status=live}}</ref><ref>{{cite news|url=http://www.extremetech.com/computing/163291-firefox-23-finally-kills-the-blink-tag-removes-ability-to-turn-off-javascript-introduces-new-logo|title=Firefox 23 finally kills the blink tag, removes ability to turn off JavaScript, introduces new logo|last=Anthony|first=Sebastian|date=August 7, 2013|newspaper=ExtremeTech|access-date=March 14, 2014|archive-url=https://web.archive.org/web/20140329071544/http://www.extremetech.com/computing/163291-firefox-23-finally-kills-the-blink-tag-removes-ability-to-turn-off-javascript-introduces-new-logo|archive-date=March 29, 2014|url-status=live}}</ref>

Beginning with Firefox 48, all extensions must be signed by Mozilla to be used in release and beta versions of Firefox.

There has been some controversy over the Mozilla Foundation's intentions in stopping certain open-source distributions from using the "Firefox" trademark.<ref name=LWNtrademark/> Open-source browsers "enable greater choice and innovation in the market rather than aiming for mass-market domination."<ref name=":0"/> Mozilla Foundation Chairperson [[Mitchell Baker]] explained in an interview in 2007 that distributions could freely use the Firefox trademark if they did not modify source code, and that the Mozilla Foundation's only concern was with users getting a consistent experience when they used "Firefox".<ref>{{cite news |first=Dan |last=Warne |title=The stoush over Linux distributions using the Firefox trademark |work=APC Magazine |publisher=ACP Magazines Ltd |date=May 7, 2007 |url=http://apcmag.com/the_stoush_over_linux_distributions_using_the_firefox_trademark.htm |access-date=January 18, 2008 |archive-url=https://web.archive.org/web/20110817064956/http://apcmag.com/the_stoush_over_linux_distributions_using_the_firefox_trademark.htm |archive-date=August 17, 2011 |url-status=live }}</ref>
To allow distributions of the code ''without'' using the official branding, the Firefox [[build automation|build system]] contains a "branding switch". This switch, often used for alphas ("Auroras") of future Firefox versions, allows the code to be compiled without the official logo and name and can allow a derivative work unencumbered by restrictions on the Firefox trademark to be produced. In the unbranded build, the trademarked logo and name are replaced with a freely distributable generic globe logo and the name of the release series from which the modified version was derived.{{Citation needed|date=September 2020}}
Distributing modified versions of Firefox under the "Firefox" name required explicit approval from Mozilla for the changes made to the underlying code, and required the use of ''all'' of the official branding. For example, it was not permissible to use the name "Firefox" without also using the official logo. When the [[Debian]] project decided to stop using the official Firefox logo in 2006 (because Mozilla's copyright restrictions at the time were incompatible with [[Debian Free Software Guidelines|Debian's guidelines]]), they were told by a representative of the Mozilla Foundation that this was not acceptable and was asked either to comply with the published trademark guidelines or cease using the "Firefox" name in their distribution.<ref>{{cite web|url=https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=354622|title=Debian Bug report logs – #354622: Uses Mozilla Firefox trademark without permission|publisher=Debian|access-date=January 30, 2007|archive-url=https://web.archive.org/web/20130206164312/http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=354622|archive-date=February 6, 2013|url-status=live}}</ref> <!-- is this important enough to include in the context of this article? - Some Debian developers had misunderstood previous communication to be an agreement that allowed them to do this, but Mozilla disputed this assertion. --> Debian switched to branding their modified version of Firefox "[[Mozilla software rebranded by Debian|Iceweasel]]" (but in 2016 switched back to Firefox), along with other Mozilla software.

=== Branding and visual identity ===
The Firefox icon is a trademark used to designate the official Mozilla build of the Firefox software and builds of official distribution partners.<ref>[https://www.mozilla.org/foundation/trademarks/distribution-policy.html Mozilla Trademark Policy for Distribution Partners] {{Webarchive|url=https://web.archive.org/web/20130402194222/https://www.mozilla.org/foundation/trademarks/distribution-policy.html |date=April 2, 2013 }} Version 0.9 (DRAFT). Retrieved November 2, 2006.</ref> For this reason, software distributors who distribute modified versions of Firefox do not use the icon.{{Citation needed|date=September 2020}}
Early Firebird and Phoenix releases of Firefox were considered to have reasonable visual designs but fell short when compared to many other professional software packages. In October 2003, professional interface designer Steven Garrity authored an article covering everything he considered to be wrong with Mozilla's visual identity.<ref name="branding-mozilla">{{cite web|last=Garrity|first=Steven|title=Branding Mozilla: Towards Mozilla 2.0|url=http://www.actsofvolition.com/files/mozillabranding/|access-date=February 8, 2009|date=October 23, 2003|archive-url=https://web.archive.org/web/20090115202336/http://www.actsofvolition.com/files/mozillabranding/|archive-date=January 15, 2009|url-status=live}}</ref>
Shortly afterwards, the Mozilla Foundation invited Garrity to head up the new visual identity team. The release of Firefox 0.8 in February 2004 saw the introduction of the new branding efforts. Included were new icon designs by silverorange, a group of web developers with a long-standing relationship with Mozilla. The final renderings are by [[Jon Hicks (designer)|Jon Hicks]], who had worked on [[Camino (web browser)|Camino]].<ref name="branding-mozilla-followup">{{cite web|url=http://www.actsofvolition.com/archive/2004/february/brandingmozilla|title=Branding Mozilla: Towards Firefox 1.0|last=Garrity|first=Steven|date=February 9, 2004|access-date=February 8, 2009|archive-url=https://web.archive.org/web/20090205043028/http://www.actsofvolition.com/archive/2004/february/brandingmozilla|archive-date=February 5, 2009|url-status=live}}</ref><ref name="branding-firefox">{{cite web|url=https://www.hicksdesign.co.uk/journal/branding-firefox|title=Branding Firefox|last=Hicks|first=Jon|date=February 9, 2004|publisher=Hicksdesign|access-date=February 8, 2009|archive-url=https://web.archive.org/web/20090208065605/http://hicksdesign.co.uk/journal/branding-firefox|archive-date=February 8, 2009|url-status=live}}</ref> The logo was later revised and updated, fixing several flaws found when it was enlarged.<ref name="spot-the-difference">{{cite web|url=https://www.hicksdesign.co.uk/journal/spot-the-difference/|title=Spot the Difference|last=Hicks|first=Jon|date=December 17, 2004|publisher=Hicksdesign|access-date=February 8, 2009|archive-url=https://web.archive.org/web/20090205061152/http://www.hicksdesign.co.uk/journal/spot-the-difference/|archive-date=February 5, 2009|url-status=live}}</ref> The animal shown in the logo is a stylized fox, although "firefox" is usually a common name for the [[red panda]].

In June 2019, Mozilla unveiled a revised Firefox logo, which was officially implemented on version 70. The new logo is part of an effort to build a brand system around Firefox and its complementary apps and services, which are now being promoted as a suite under the Firefox brand.

In January 2010, Lifehacker compared the performance of Firefox 3.5, Firefox 3.6, Google Chrome 4 (stable and Dev versions), Safari 4, and Opera (10.1 stable and 10.5 pre-alpha versions). Lifehacker timed how long browsers took to start and reach a page (both right after boot-up and after running at least once already), timed how long browsers took to load nine tabs at once, tested JavaScript speeds using Mozilla's Dromaeo online suite (which implements Apple's [[Browser speed test#Apple benchmarks|SunSpider]] and Google's V8 tests) and measured memory usage using Windows 7's process manager. They concluded that Firefox 3.5 and 3.6 were the fifth- and sixth-fastest browsers, respectively, on startup, 3.5 was third- and 3.6 was sixth-fastest to load nine tabs at once, 3.5 was sixth- and 3.6 was fifth-fastest on the JavaScript tests. They also concluded that Firefox 3.6 was the most efficient with memory usage followed by Firefox 3.5.<ref>{{cite news|url=https://lifehacker.com/5457242/browser-speed-tests-firefox-36-chrome-4-opera-105-and-extensions|title=Browser Speed Tests: Firefox 3.6, Chrome 4, Opera 10.5, and Extensions|last=Purdy|first=Kevin|date=January 26, 2010|access-date=May 4, 2010|publisher=Lifehacker|archive-url=https://web.archive.org/web/20100504143754/http://lifehacker.com/5457242/browser-speed-tests-firefox-36-chrome-4-opera-105-and-extensions|archive-date=May 4, 2010|url-status=live}}</ref>
In February 2012, ''[[Tom's Hardware]]'' performance tested Chrome 17, Firefox 10, [[Internet Explorer 9]], Opera 11.61, and Safari 5.1.2 on Windows 7. ''Tom's Hardware'' summarized their tests into four categories: Performance, Efficiency, Reliability, and Conformance. In the performance category they tested [[HTML5]], [[Java (software platform)|Java]], [[JavaScript]], [[Document Object Model|DOM]], [[CSS 3]], [[Adobe Flash|Flash]], [[Silverlight]], and [[WebGL]] ([[WebGL 2]] is current as of version 51; and Java and Silverlight stop working as of version 52)—they also tested startup time and page load time. The performance tests showed that Firefox was either "acceptable" or "strong" in most categories, winning three categories (HTML5, HTML5 [[hardware acceleration]], and Java) only finishing "weak" in CSS performance. In the efficiency tests, ''Tom's Hardware'' tested memory usage and management. In this category, it determined that Firefox was only "acceptable" at performing light memory usage, while it was "strong" at performing heavy memory usage. In the reliability category, Firefox performed a "strong" amount of proper page loads. In the final category, conformance, it was determined that Firefox had "strong" conformance for JavaScript and HTML5. In conclusion, ''Tom's Hardware'' determined that Firefox was the best browser for Windows 7 OS, but that it only narrowly beat Google Chrome.<ref>{{cite web|url=https://www.tomshardware.com/reviews/chrome-17-firefox-10-ubuntu,3129-17.html|title=Benchmark Analysis: Windows 7 and Ubuntu 11.10|last=Overa|first=Adam|date=February 21, 2012|publisher=Tom's Hardware|access-date=April 8, 2012|archive-date=September 13, 2012|archive-url=https://archive.today/20120913011235/http://www.tomshardware.com/reviews/chrome-17-firefox-10-ubuntu,3129-17.html|url-status=live}}</ref>
In June 2013, ''Tom's Hardware'' again performance tested Firefox 22, Chrome 27, Opera 12, and [[Internet Explorer 10]]. They found that Firefox slightly edged out the other browsers in their "performance" index, which examined wait times, JavaScript execution speed, HTML5/CSS3 rendering, and hardware acceleration performance. Firefox also scored the highest on the "non-performance" index, which measured memory efficiency, reliability, security, and standards conformance, finishing ahead of Chrome, the runner-up. ''Tom's Hardware'' concluded by declaring Firefox the "sound" winner of the performance benchmarks.<ref name="Overa13">{{cite news|url=https://www.tomshardware.com/reviews/chrome-27-firefox-21-opera-next,3534-12.html|title=Chrome 27, Firefox 22, IE10, And Opera Next, Benchmarked|last=Overa|first=Adam|date=June 30, 2013|newspaper=Tom's Hardware|access-date=May 2, 2014|archive-date=July 3, 2013|archive-url=https://archive.today/20130703091630/http://www.tomshardware.com/reviews/chrome-27-firefox-21-opera-next,3534-12.html|url-status=live}}</ref>

In benchmark testing in early 2015 on a "high-end" Windows machine, comparing [[Microsoft Edge]], Internet Explorer, Firefox, Chrome, and Opera, Firefox achieved the highest score on three of the seven tests. Four different JavaScript performance tests gave conflicting results. Firefox surpassed all other browsers on the [[Browser speed test|Peacekeeper benchmark]] but was behind the Microsoft products when tested with SunSpider. Measured with Mozilla's Kraken, it came second place to Chrome, while on Google's [[Browser speed test#Octane|Octane]] challenge it took third behind Chrome and Opera. Firefox took the lead with WebXPRT, which runs several typical HTML5 and JavaScript tasks. Firefox, Chrome, and Opera all achieved the highest possible score on the Oort Online test, measuring WebGL rendering speed (WebGL 2 is now current). In terms of HTML5 compatibility testing, Firefox was ranked in the middle of the group.<ref name="TekRevue-2015-04-01">{{cite web|url=https://www.tekrevue.com/spartan-benchmarks-ie-chrome-firefox-opera/|title=Spartan Benchmarks: Spartan vs. IE, Chrome, Firefox, and Opera|last=Tanous|first=Jim|date=April 1, 2015|website=TekRevue|access-date=January 10, 2016|archive-url=https://web.archive.org/web/20151226174659/http://www.tekrevue.com/spartan-benchmarks-ie-chrome-firefox-opera/|archive-date=December 26, 2015|url-status=live}}</ref>
A similar set of benchmark tests in 2016 showed Firefox's JavaScript performance on Kraken and the newer [[Browser speed test#JetStream|Jetstream]] tests trailing slightly behind all other tested browsers except Internet Explorer (IE), which performed relatively poorly.

</p><p>Version 1.0 of Firefox was released on November 9, 2004.<sup id="cite_ref-15" class="reference"><a href="#cite_note-15">[15]</a></sup> This was followed by version 1.5 in November 2005, version 2.0 in October 2006, version 3.0 in June 2008, version 3.5 in June 2009, version 3.6 in January 2010, and version 4.0 in March 2011. From version 5 onwards, the development and release model changed into a "rapid" one; by the end of 2011 the stable release was version 9, and by the end of 2012 it reached version 17.<sup id="cite_ref-16" class="reference"><a href="#cite_note-16">[16]</a></sup>

</p><p>In 2016, Mozilla announced a project known as <a href="/enwiki/wiki/Quantum_(Mozilla)" class="mw-redirect" title="Quantum (Mozilla)">Quantum</a>, which sought to improve Firefox's Gecko engine and other components to improve the browser's performance, modernize its architecture, and transition the browser to a <a href="/enwiki/wiki/Process_isolation" title="Process isolation">multi-process</a> model. These improvements came in the wake of decreasing market share to <a href="/enwiki/wiki/Google_Chrome" title="Google Chrome">Google Chrome</a>, as well as concerns that its performance was lapsing in comparison. Despite its improvements, these changes required existing <a href="/enwiki/wiki/Add-on_(Mozilla)" title="Add-on (Mozilla)">add-ons</a> for Firefox to be made incompatible with newer versions, in favor of a new <a href="/enwiki/wiki/Browser_extension" title="Browser extension">extension</a> system that is designed to be similar to Chrome and other recent browsers. Firefox 57, which was released in November 2017, was the first version to contain enhancements from Quantum, and has thus been named <i>Firefox Quantum</i>. A Mozilla executive stated that Quantum was the "biggest update" to the browser since version 1.0.<sup id="cite_ref-cnet57_17-0" class="reference"><a href="#cite_note-cnet57-17">[17]</a></sup><sup id="cite_ref-18" class="reference"><a href="#cite_note-18">[18]</a></sup><sup id="cite_ref-19" class="reference"><a href="#cite_note-19">[19]</a></sup> Unresponsive and crashing pages only affect other pages loaded within the same process. While Chrome uses separate processes for each loaded tab, Firefox distributes tabs over four processes by default since Quantum in order to balance memory consumption and performance. The process count can be adjusted, where more processes increase performance at the cost of memory, therefore suitable for computers with larger RAM capacity.<sup id="cite_ref-20" class="reference"><a href="#cite_note-20">[20]</a></sup><sup id="cite_ref-21" class="reference"><a href="#cite_note-21">[21]</a></sup>

Additionally, <a href="/enwiki/wiki/JavaScript" title="JavaScript">JavaScript</a> could also no longer be disabled through Firefox's preferences, and JavaScript was automatically re-enabled for users who upgraded to 23 or higher with it disabled.

<p>Since its inception, Firefox for Linux supported the 32-bit memory architecture of the IA-32 instruction set. 64-bit builds were introduced in the 4.0 release.<sup id="cite_ref-maclinux64_152-1" class="reference"><a href="#cite_note-maclinux64-152">[152]</a></sup> The 46.0 release replaced <a href="/enwiki/wiki/GTK" title="GTK">GTK</a> 2.18 with 3.4 as a system requirement on Linux and other systems running X.Org.<sup id="cite_ref-164" class="reference"><a href="#cite_note-164">[164]</a></sup> Starting with 53.0, the 32-bit builds require the <a href="/enwiki/wiki/SSE2" title="SSE2">SSE2</a> instruction set.

<p>Firefox for mobile is a web browser for mobile phones, tablets, and PDAs. It was originally first released for the <a href="/enwiki/wiki/Nokia" title="Nokia">Nokia</a> <a href="/enwiki/wiki/Maemo" title="Maemo">Maemo</a> operating system, specifically the Nokia N900, on January 28, 2010.<sup id="cite_ref-165" class="reference"><a href="#cite_note-165">[165]</a></sup> On March 29, 2011, an Android version was released, being based on version 4.<sup id="cite_ref-ff4_166-0" class="reference"><a href="#cite_note-ff4-166">[166]</a></sup> With the release of the mobile version, the browser's version number was bumped from 2 to 4, synchronizing it with all future desktop releases of Firefox because the rendering engines used in both browsers are the same.<sup id="cite_ref-167" class="reference"><a href="#cite_note-167">[167]</a></sup> Version 7 was the last release for Maemo on the N900.<sup id="cite_ref-168" class="reference"><a href="#cite_note-168">[168]</a></sup>
</p><p>The former Firefox for <a href="/enwiki/wiki/Android_(operating_system)" title="Android (operating system)">Android</a> (codenamed <a href="/enwiki/wiki/Firefox_for_Android" title="Firefox for Android">Fennec</a>), was a web browser for Android devices, such as mobile phones and tablets. Its user interface was optimized for small screens and tablets. It included the Awesome Bar, tabbed browsing, add-on support, a password manager, location-aware browsing, and the ability to synchronize with the user's other devices with Mozilla Firefox using <a href="/enwiki/wiki/Firefox_Sync" title="Firefox Sync">Firefox Sync</a>.<sup id="cite_ref-169" class="reference"><a href="#cite_note-169">[169]</a></sup> It was criticized for being slow,<sup id="cite_ref-170" class="reference"><a href="#cite_note-170">[170]</a></sup> however, in part due to its poor port of Gecko.<sup id="cite_ref-auto_171-0" class="reference"><a href="#cite_note-auto-171">[171]</a></sup> At the end of its existence, it had a marketshare of 0.5% on Android.<sup id="cite_ref-172" class="reference"><a href="#cite_note-172">[172]</a></sup>
</p><p>In April 2013, then-Mozilla CEO <a href="/enwiki/wiki/Gary_Kovacs" title="Gary Kovacs">Gary Kovacs</a> said that Firefox would not come to iOS if Apple required the use of the <a href="/enwiki/wiki/WebKit" title="WebKit">WebKit</a> layout engine to do so. One reason given by Mozilla was that prior to iOS 8, Apple had supplied third-party browsers with an inferior version of their JavaScript engine which hobbled their performance, making it impossible to match Safari's JavaScript performance on the iOS platform.<sup id="cite_ref-173" class="reference"><a href="#cite_note-173">[173]</a></sup> Apple later opened their "Nitro" JavaScript engine to third-party browsers.<sup id="cite_ref-174" class="reference"><a href="#cite_note-174">[174]</a></sup> In 2015, Mozilla announced it was moving forward with Firefox for iOS, with a preview release made available in New Zealand in September of that year.<sup id="cite_ref-175" class="reference"><a href="#cite_note-175">[175]</a></sup><sup id="cite_ref-176" class="reference"><a href="#cite_note-176">[176]</a></sup><sup id="cite_ref-177" class="reference"><a href="#cite_note-177">[177]</a></sup> It fully released in November later that year.<sup id="cite_ref-178" class="reference"><a href="#cite_note-178">[178]</a></sup> In November 2016, Firefox released a new iOS app titled <a href="/enwiki/wiki/Firefox_Focus" title="Firefox Focus">Firefox Focus</a>, a private web browser.<sup id="cite_ref-179" class="reference"><a href="#cite_note-179">[179]</a></sup>
</p><p>In August 2020, Mozilla launched a new version of its <a href="/enwiki/wiki/Firefox_for_Android" title="Firefox for Android">Firefox for Android</a> app, named Firefox Daylight to the public<sup id="cite_ref-Zare_180-0" class="reference"><a href="#cite_note-Zare-180">[180]</a></sup> and codenamed <a href="/enwiki/wiki/Firefox_for_Android" title="Firefox for Android">Fenix</a>,<sup id="cite_ref-181" class="reference"><a href="#cite_note-181">[181]</a></sup> after a little over a year of testing.<sup id="cite_ref-auto_171-1" class="reference"><a href="#cite_note-auto-171">[171]</a></sup> It boasted higher speeds with its new <a href="/enwiki/wiki/GeckoView" class="mw-redirect" title="GeckoView">GeckoView engine</a>, which is described as being "the only independent <a href="/enwiki/wiki/Browser_engine" title="Browser engine">web engine browser</a> available on <a href="/enwiki/wiki/Android_(operating_system)" title="Android (operating system)">Android</a>".

<p>There has been some controversy over the Mozilla Foundation's intentions in stopping certain open-source distributions from using the "Firefox" trademark.<sup id="cite_ref-LWNtrademark_229-0" class="reference"><a href="#cite_note-LWNtrademark-229">[229]</a></sup> Open-source browsers "enable greater choice and innovation in the market rather than aiming for mass-market domination."<sup id="cite_ref-:0_230-0" class="reference"><a href="#cite_note-:0-230">[230]</a></sup> Mozilla Foundation Chairperson <a href="/enwiki/wiki/Mitchell_Baker" title="Mitchell Baker">Mitchell Baker</a> explained in an interview in 2007 that distributions could freely use the Firefox trademark if they did not modify source code, and that the Mozilla Foundation's only concern was with users getting a consistent experience when they used "Firefox".<sup id="cite_ref-231" class="reference"><a href="#cite_note-231">[231]</a></sup>
</p><p>To allow distributions of the code <i>without</i> using the official branding, the Firefox <a href="/enwiki/wiki/Build_automation" title="Build automation">build system</a> contains a "branding switch". This switch, often used for alphas ("Auroras") of future Firefox versions, allows the code to be compiled without the official logo and name and can allow a derivative work unencumbered by restrictions on the Firefox trademark to be produced. In the unbranded build, the trademarked logo and name are replaced with a freely distributable generic globe logo and the name of the release series from which the modified version was derived.<sup class="noprint Inline-Template Template-Fact" style="white-space:nowrap;">[<i><a href="/enwiki/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed"><span title="This claim needs references to reliable sources.

</p><p>Distributing modified versions of Firefox under the "Firefox" name required explicit approval from Mozilla for the changes made to the underlying code, and required the use of <i>all</i> of the official branding. For example, it was not permissible to use the name "Firefox" without also using the official logo. When the <a href="/enwiki/wiki/Debian" title="Debian">Debian</a> project decided to stop using the official Firefox logo in 2006 (because Mozilla's copyright restrictions at the time were incompatible with <a href="/enwiki/wiki/Debian_Free_Software_Guidelines" title="Debian Free Software Guidelines">Debian's guidelines</a>), they were told by a representative of the Mozilla Foundation that this was not acceptable and was asked either to comply with the published trademark guidelines or cease using the "Firefox" name in their distribution.<sup id="cite_ref-232" class="reference"><a href="#cite_note-232">[232]</a></sup> Debian switched to branding their modified version of Firefox "<a href="/enwiki/wiki/Mozilla_software_rebranded_by_Debian" title="Mozilla software rebranded by Debian">Iceweasel</a>" (but in 2016 switched back to Firefox), along with other Mozilla software. <a href="/enwiki/wiki/GNU_IceCat" title="GNU IceCat">GNU IceCat</a> is another derived version of Firefox distributed by the <a href="/enwiki/wiki/GNU_Project" title="GNU Project">GNU Project</a>, which maintains its separate branding.<sup id="cite_ref-233" class="reference"><a href="#cite_note-233">[233]</a></sup>

</p><p>Early Firebird and Phoenix releases of Firefox were considered to have reasonable visual designs but fell short when compared to many other professional software packages. In October 2003, professional interface designer Steven Garrity authored an article covering everything he considered to be wrong with Mozilla's visual identity.<sup id="cite_ref-branding-mozilla_235-0" class="reference"><a href="#cite_note-branding-mozilla-235">[235]</a></sup>
</p><p>Shortly afterwards, the Mozilla Foundation invited Garrity to head up the new visual identity team. The release of Firefox 0.8 in February 2004 saw the introduction of the new branding efforts. Included were new icon designs by silverorange, a group of web developers with a long-standing relationship with Mozilla. The final renderings are by <a href="/enwiki/wiki/Jon_Hicks_(designer)" title="Jon Hicks (designer)">Jon Hicks</a>, who had worked on <a href="/enwiki/wiki/Camino_(web_browser)" title="Camino (web browser)">Camino</a>.<sup id="cite_ref-branding-mozilla-followup_236-0" class="reference"><a href="#cite_note-branding-mozilla-followup-236">[236]</a></sup><sup id="cite_ref-branding-firefox_237-0" class="reference"><a href="#cite_note-branding-firefox-237">[237]</a></sup> The logo was later revised and updated, fixing several flaws found when it was enlarged.<sup id="cite_ref-spot-the-difference_238-0" class="reference"><a href="#cite_note-spot-the-difference-238">[238]</a></sup> The animal shown in the logo is a stylized fox, although "firefox" is usually a common name for the <a href="/enwiki/wiki/Red_panda" title="Red panda">red panda</a>. The panda, according to Hicks, "didn't really conjure up the right imagery" and was not widely known.<sup id="cite_ref-branding-firefox_237-1" class="reference"><a href="#cite_note-branding-firefox-237">[237]</a></sup>
</p><p>In June 2019, Mozilla unveiled a revised Firefox logo, which was officially implemented on version 70. The new logo is part of an effort to build a brand system around Firefox and its complementary apps and services, which are now being promoted as a suite under the Firefox brand.

<p>In January 2010, Lifehacker compared the performance of Firefox 3.5, Firefox 3.6, Google Chrome 4 (stable and Dev versions), Safari 4, and Opera (10.1 stable and 10.5 pre-alpha versions). Lifehacker timed how long browsers took to start and reach a page (both right after boot-up and after running at least once already), timed how long browsers took to load nine tabs at once, tested JavaScript speeds using Mozilla's Dromaeo online suite (which implements Apple's <a href="/enwiki/wiki/Browser_speed_test#Apple_benchmarks" title="Browser speed test">SunSpider</a> and Google's V8 tests) and measured memory usage using Windows 7's process manager. They concluded that Firefox 3.5 and 3.6 were the fifth- and sixth-fastest browsers, respectively, on startup, 3.5 was third- and 3.6 was sixth-fastest to load nine tabs at once, 3.5 was sixth- and 3.6 was fifth-fastest on the JavaScript tests. They also concluded that Firefox 3.6 was the most efficient with memory usage followed by Firefox 3.5.<sup id="cite_ref-270" class="reference"><a href="#cite_note-270">[270]</a></sup>
</p><p>In February 2012, <i><a href="/enwiki/wiki/Tom%27s_Hardware" title="Tom's Hardware">Tom's Hardware</a></i> performance tested Chrome 17, Firefox 10, <a href="/enwiki/wiki/Internet_Explorer_9" title="Internet Explorer 9">Internet Explorer 9</a>, Opera 11.61, and Safari 5.1.2 on Windows 7. <i>Tom's Hardware</i> summarized their tests into four categories: Performance, Efficiency, Reliability, and Conformance. In the performance category they tested <a href="/enwiki/wiki/HTML5" title="HTML5">HTML5</a>, <a href="/enwiki/wiki/Java_(software_platform)" title="Java (software platform)">Java</a>, <a href="/enwiki/wiki/JavaScript" title="JavaScript">JavaScript</a>, <a href="/enwiki/wiki/Document_Object_Model" title="Document Object Model">DOM</a>, <a href="/enwiki/wiki/CSS_3" class="mw-redirect" title="CSS 3">CSS 3</a>, <a href="/enwiki/wiki/Adobe_Flash" title="Adobe Flash">Flash</a>, <a href="/enwiki/wiki/Silverlight" class="mw-redirect" title="Silverlight">Silverlight</a>, and <a href="/enwiki/wiki/WebGL" title="WebGL">WebGL</a> (<a href="/enwiki/wiki/WebGL_2" class="mw-redirect" title="WebGL 2">WebGL 2</a> is current as of version 51; and Java and Silverlight stop working as of version 52)—they also tested startup time and page load time. The performance tests showed that Firefox was either "acceptable" or "strong" in most categories, winning three categories (HTML5, HTML5 <a href="/enwiki/wiki/Hardware_acceleration" title="Hardware acceleration">hardware acceleration</a>, and Java) only finishing "weak" in CSS performance. In the efficiency tests, <i>Tom's Hardware</i> tested memory usage and management. In this category, it determined that Firefox was only "acceptable" at performing light memory usage, while it was "strong" at performing heavy memory usage. In the reliability category, Firefox performed a "strong" amount of proper page loads. In the final category, conformance, it was determined that Firefox had "strong" conformance for JavaScript and HTML5. In conclusion, <i>Tom's Hardware</i> determined that Firefox was the best browser for Windows 7 OS, but that it only narrowly beat Google Chrome.<sup id="cite_ref-271" class="reference"><a href="#cite_note-271">[271]</a></sup>
</p><p>In June 2013, <i>Tom's Hardware</i> again performance tested Firefox 22, Chrome 27, Opera 12, and <a href="/enwiki/wiki/Internet_Explorer_10" title="Internet Explorer 10">Internet Explorer 10</a>. They found that Firefox slightly edged out the other browsers in their "performance" index, which examined wait times, JavaScript execution speed, HTML5/CSS3 rendering, and hardware acceleration performance. Firefox also scored the highest on the "non-performance" index, which measured memory efficiency, reliability, security, and standards conformance, finishing ahead of Chrome, the runner-up. <i>Tom's Hardware</i> concluded by declaring Firefox the "sound" winner of the performance benchmarks.<sup id="cite_ref-Overa13_272-0" class="reference"><a href="#cite_note-Overa13-272">[272]</a></sup>
</p><p>In January 2014, a benchmark testing the memory usage of Firefox 29, Google Chrome 34, and <a href="/enwiki/wiki/Internet_Explorer_11" title="Internet Explorer 11">Internet Explorer 11</a> indicated that Firefox used the least memory when a substantial number of tabs were open.<sup id="cite_ref-Brinkmann14_273-0" class="reference"><a href="#cite_note-Brinkmann14-273">[273]</a></sup>
</p><p>In benchmark testing in early 2015 on a "high-end" Windows machine, comparing <a href="/enwiki/wiki/Microsoft_Edge" title="Microsoft Edge">Microsoft Edge</a>, Internet Explorer, Firefox, Chrome, and Opera, Firefox achieved the highest score on three of the seven tests. Four different JavaScript performance tests gave conflicting results. Firefox surpassed all other browsers on the <a href="/enwiki/wiki/Browser_speed_test" title="Browser speed test">Peacekeeper benchmark</a> but was behind the Microsoft products when tested with SunSpider. Measured with Mozilla's Kraken, it came second place to Chrome, while on Google's <a href="/enwiki/wiki/Browser_speed_test#Octane" title="Browser speed test">Octane</a> challenge it took third behind Chrome and Opera. Firefox took the lead with WebXPRT, which runs several typical HTML5 and JavaScript tasks. Firefox, Chrome, and Opera all achieved the highest possible score on the Oort Online test, measuring WebGL rendering speed (WebGL 2 is now current). In terms of HTML5 compatibility testing, Firefox was ranked in the middle of the group.<sup id="cite_ref-TekRevue-2015-04-01_274-0" class="reference"><a href="#cite_note-TekRevue-2015-04-01-274">[274]</a></sup>
</p><p>A similar set of benchmark tests in 2016 showed Firefox's JavaScript performance on Kraken and the newer <a href="/enwiki/wiki/Browser_speed_test#JetStream" title="Browser speed test">Jetstream</a> tests trailing slightly behind all other tested browsers except Internet Explorer (IE), which performed relatively poorly. On Octane, Firefox came ahead of IE and Safari, but again slightly behind the rest, including <a href="/enwiki/wiki/Vivaldi_(web_browser)" title="Vivaldi (web browser)">Vivaldi</a> and Microsoft Edge.
