Mozilla Firefox is more than just a browser; it&#;s a statement of freedom, a champion of open source, and a testimony to how community efforts can create a powerhouse. At the heart of this brand is its emblem, the Mozilla Firefox logo, a visual identity known by web surfers worldwide. The logo encapsulates the brand&#;s ethos, and its evolution over the years mirrors the browser&#;s journey from a Phoenix to the fox encircling the globe today. This article delves into the Mozilla Firefox logo&#;s history, dissecting its evolution, and the meaning embedded in its design.

Mozilla Firefox Logo Meaning and History

The Mozilla Firefox logo is not merely a stylized fox encircling a globe. It&#;s a narrative of the browser&#;s heritage, the community that propels it forward, and the brand&#;s mission to create a web where individuals have control. The logo has seen several transitions, each portraying a new chapter in the browser&#;s saga.

–

The inception of the Firefox logo dates back to when it was first known as Phoenix. However, the browser had to change its name and identity due to trademark issues. The name transitioned from Phoenix to Firebird, and eventually to Firefox. This period marked the birth of the iconic logo we&#;re familiar with today. The first version of the Firefox logo depicted a Phoenix, symbolizing the brand&#;s rise from the ashes, ready to take on the world.

–

During this period, the transition from a mythical bird to a fox took place. The new logo showcased a swift fox encircling the globe, symbolizing speed, accuracy, and the global reach of the browser. This change was not just about aesthetics but was a nod to the browser&#;s improved capabilities and expanding user base. The globe in the logo represented the worldwide web, emphasizing Mozilla Firefox&#;s promise to provide an open, accessible, and user-friendly browser for everyone across the globe.

–

The logo underwent subtle refinements to depict a more modern and professional look. The fox&#;s rendering became more detailed, and the color palette became brighter and more engaging. These changes reflected Mozilla Firefox&#;s growing maturity and its solidifying position as a reputable browser. The design tweaks during this period were more about fine-tuning the logo to resonate better with the evolving aesthetics of the digital age.

–

During this phase, the logo saw further refinements in terms of color gradient and detailing. The tweaks were subtle but aimed at keeping the logo contemporary and reflective of the browser&#;s continuous improvements. The emblem continued to maintain its iconic fox and globe imagery, a testimony to the brand&#;s consistent vision.

–

As design trends shifted towards a flatter, minimalist aesthetic, the Mozilla Firefox logo too was streamlined. The details were simplified, and the colors were made more vibrant to align with modern design sensibilities. This period saw a shift towards a cleaner and more modern logo, aligning with the browser’s evolving features and the industry&#;s design trends.

–

In these years, the logo maintained its flat design but with an even more simplified and modern look. The fox&#;s depiction became more abstract, and the color palette was refreshed to keep up with the modern design aesthetics. These alterations were a reflection of Mozilla Firefox&#;s commitment to staying updated and relevant in the fast-evolving digital landscape.

– Present

In the most recent update, the logo evolved to become more simplistic and abstract, yet maintaining its iconic imagery. The fox tail became a fluid line, encircling a gradient globe. This change, while subtle, symbolized a more modern, faster, and streamlined browser experience. The logo today stands as a symbol of reliability, speed, and the global community that continues to support and develop the Mozilla Firefox browser.

Each phase of the logo’s evolution tells a story of the brand&#;s journey, its challenges, and its commitment to delivering a browser that prioritizes user freedom and global accessibility.

logo historyMozilla Firefox

Mozilla Firefox is a fast, light and tidy open source web browser. At its public launch in Mozilla Firefox was the first browser to challenge Microsoft Internet Explorer’s dominance. Since then, Mozilla Firefox has consistently featured in the top 3 most popular browsers globally and this is set to continue thanks to the release of Firefox The key features that have made Mozilla Firefox so popular are the simple and effective UI, browser speed and strong security capabilities. The browser is particularly popular with developers thanks to its open source development and active community of advanced users.

Easier Browsing

Mozilla put of a lot of resources into creating a simple but effective UI aimed at making browsing quicker and easier. They created the tab structure that has been adopted by most other browsers. In recent years Mozilla has also focused on maximizing browsing area by simplifying toolbar controls to just a Firefox button (which contains settings and options) and back/forward buttons. The URL box features direct Google searching as well as an auto predict/history feature called Awesome Bar. On the right side of the URL box there are bookmarking, history and refresh buttons. To the right of the URL box is a search box which allows you to customize your search engine options. Outside of that a view button controls what you see below the URL. Next to that you have the download history and home buttons.

Speed

Mozilla Firefox boasts impressive page load speeds thanks to the excellent JagerMonkey JavaScript engine. Start up speed and graphics rendering are also among the quickest in the market. Firefox manages complex video and web content using layer-based Direct2D and Driect3D graphics systems. Crash protection ensures only the plugin causing the issue stops working, not the rest of the content being browsed. Reloading the page restarts any affected plugins. The tab system and Awesome Bar have been streamlined to launch/get results very quickly too.

Security

Firefox was the first browser to introduce a private browsing feature which allows you to use the internet more anonymously and securely. History, searches, passwords, downloads, cookies and cached content are all removed on shutdown. Minimizing the chances of another user stealing your identity or finding confidential information. Content security, anti-phishing technology and antivirus/antimalware integration ensures your browsing experience is as safe as possible.

Personalisation & Development

One of the best features of the Firefox UI is customization. Simply right click on the navigation toolbar to customize individual components or just drag and drop items you want to move around. The inbuilt Firefox Add-ons Manager allows you to discover and install add-ons within the browser as well as view ratings, recommendations and descriptions. Read about the top recommended add-ons for Mozilla Firefox on TechBeat. Thousands of customizable themes allow you to customize the look and feel of your browser. Site authors and developers can create advanced content and applications using Mozilla’s open source platform and enhanced API.

Mozilla Firefox, or simply Firefox, is a free and open-source^[11]web browser developed by the Mozilla Foundation and its subsidiary, the Mozilla Corporation. It uses the Geckorendering engine to display web pages, which implements current and anticipated web standards.^[12] Firefox is available for Windows 10 or later versions, macOS, and Linux. Its unofficial ports are available for various Unix and Unix-like operating systems, including FreeBSD,^[13]OpenBSD,^[14]NetBSD,^[15]illumos,^[16] and Solaris Unix.^[17] It is also available for Android and iOS. However, as with all other iOS web browsers, the iOS version uses the WebKit layout engine instead of Gecko due to platform requirements. An optimized version is also available on the Amazon Fire TV as one of the two main browsers available with Amazon's Silk Browser.^[18]

Firefox is the spiritual successor of Netscape Navigator, as the Mozilla community was created by Netscape in , before its acquisition by AOL.^[19] Firefox was created in under the codename "Phoenix" by members of the Mozilla community who desired a standalone browser rather than the Mozilla Application Suite bundle. During its beta phase, it proved to be popular with its testers and was praised for its speed, security, and add-ons compared to Microsoft's then-dominant Internet Explorer&#;6. It was released on November 9, ,^[20] and challenged Internet Explorer's dominance with 60&#;million downloads within nine months.^[21] In November , Firefox began incorporating new technology under the code name "Quantum" to promote parallelism and a more intuitive user interface.^[22]

Firefox usage share grew to a peak of % in November ,^[23] with Firefox overtaking Internet Explorer 7, although not all versions of Internet Explorer as a whole;^[24][25] its usage then declined in competition with Google Chrome.^[23] As of December&#;^[update], according to StatCounter, it had a % usage share on traditional PCs (i.e. as a desktop browser), making it the fourth-most popular PC web browser after Google Chrome (62%), Safari (13%), and Microsoft Edge (11%).^[26][27]

History[edit]

See also: Firefox early version history and Firefox version history

The project began as an experimental branch of the Mozilla project by Dave Hyatt, Joe Hewitt, and Blake Ross. They believed the commercial requirements of Netscape's sponsorship and developer-driven feature creep compromised the utility of the Mozilla browser.^[28] To combat what they saw as the Mozilla Suite's software bloat, they created a standalone browser, with which they intended to replace the Mozilla Suite.^[29] Version was released on September 23, ^[30] On April 3, , the Mozilla Organization announced that it planned to change its focus from the Mozilla Suite to Firefox and Thunderbird.^[31]

The Firefox project has undergone several name changes.^[32] The nascent browser was originally named Phoenix, after the mythical bird that rose triumphantly from the ashes of its dead predecessor (in this case, from the "ashes" of Netscape Navigator, after it was sidelined by Microsoft Internet Explorer in the "First Browser War"). Phoenix was renamed in due to a trademark claim from Phoenix Technologies. The replacement name, Firebird, provoked an intense response from the Firebird database software project.^[33][34] The Mozilla Foundation reassured them that the browser would always bear the name Mozilla Firebird to avoid confusion. After further pressure, Mozilla Firebird became Mozilla Firefox on February 9, ^[35] The name Firefox was said to be derived from a nickname of the red panda,^[36] which became the mascot for the newly named project.^[37] For the abbreviation of Firefox, Mozilla prefers Fx or fx, although it is often abbreviated as FF.^[38]

The Firefox project went through many versions before version and had already gained a great deal of acclaim from numerous media outlets, such as Forbes^[39] and The Wall Street Journal.^[40] Among Firefox's popular features were the integrated pop-up blocker, tabbed browsing, and an extension mechanism for adding functionality. Although these features have already been available for some time in other browsers such as the Mozilla Suite and Opera, Firefox was the first of these browsers to have achieved large-scale adoption.^{[citation needed]} Firefox attracted attention as an alternative to Internet Explorer, which had come under fire for its alleged poor program design and insecurity—detractors cite IE's lack of support for certain Web standards, use of the potentially dangerous ActiveX component, and vulnerability to spyware and malware installation.^{[citation needed]} Microsoft responded by releasing Windows XP Service Pack 2, which added several important security features to Internet Explorer 6.^[41]

Version of Firefox was released on November 9, ^[42] This was followed by version in November , version in October , version in June , version in June , version in January , and version in March From version 5 onwards, the development and release model changed into a "rapid" one; by the end of the stable release was version 9, and by the end of it reached version ^[43]

Major redesigns of its graphical user interface occurred on versions (Strata) in March , (Australis) in April , (Photon) in November , and (Proton) in June

In , Mozilla announced a project known as 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 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-ons for Firefox to be made incompatible with newer versions, in favor of a new extension system that is designed to be similar to Chrome and other recent browsers. Firefox 57, which was released in November , 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 ^[44][45][46] 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.^[47][48]

On May 3, , the expiration of an intermediate signing certificate on Mozilla servers caused Firefox to automatically disable and lock all browser extensions (add-ons).^[49][50] Mozilla began the roll-out of a fix shortly thereafter, using their Mozilla Studies component.^[49][50]

Support for Adobe Flash was dropped on January 6, , with the release of Firefox ^[51]

On January 13, , an issue with Firefox's HTTP/3 implementation resulted in a widespread outage for multiple hours.^[52]

On January 23, , along with the release of Firefox , Mozilla introduced an official APT repository for Debian-based Linux distributions.^[53]

Features[edit]

Main article: Features of Firefox

Features of the desktop edition include tabbed browsing, full-screen mode, spell checking, incremental search, smart bookmarks, bookmarking and downloading through drag and drop,^[54][55] a download manager, user profile management,^[56]private browsing, bookmark tags, bookmark exporting,^[57] offline mode,^[58] a screenshot tool, web development tools, a "page info" feature which shows a list of page metadata and multimedia items,^[59] a sophisticated configuration menu at for power users, and more location-aware browsing (also known as "geolocation") based on a Google service.^[60] Firefox has an integrated search system which uses Google by default in most markets but an update for American users in made it start including paid promotions by default in its suggestions.^[61][62]DNS over HTTPS is another feature whose default behaviour is determined geographically.^[63]

Firefox provides an environment for web developers in which they can use built-in tools, such as the Error Console or the DOM Inspector, and extensions, such as Firebug and more recently there has been an integration feature with Pocket. Firefox Hello was an implementation of WebRTC, added in October , which allows users of Firefox and other compatible systems to have a video call, with the extra feature of screen and file sharing by sending a link to each other. Firefox Hello was scheduled to be removed in September ^[64]

Former features include a File Transfer Protocol (FTP) client for browsing file servers, the ability to block images from individual domains (until version 72),^[65] a 3D page inspector (versions 11 to 46), tab grouping (until version 44), and the ability to add customized extra toolbars (until version 28).^[66][67][68]

Browser extensions[edit]

Functions can be added through add-ons created by third-party developers. Add-ons are primarily coded using an HTML, CSS, JavaScript, with API known as WebExtensions, which is designed to be compatible with Google Chrome and Microsoft Edge extension systems.^[69] Firefox previously supported add-ons using the XUL and XPCOM APIs, which allowed them to directly access and manipulate much of the browser's internal functionality. As compatibility was not included in the multi-process architecture, XUL add-ons have been deemed Legacy add-ons and are no longer supported on Firefox 57 "Quantum" and newer.^[70][71]

Mozilla has occasionally installed extensions for users without their permission. This happened in when an extension designed to promote the show Mr. Robot was silently added in an update to Firefox.^[72][73]

Themes[edit]

Firefox can have themes added to it, which users can create or download from third parties to change the appearance of the browser.^[74][75]

Guest session[edit]

In , Firefox for Android added a guest session mode, which wiped browsing data such as tabs, cookies, and history at the end of each guest session. Guest session data was kept even when restarting the browser or device, and deleted only upon a manual exit. The feature was removed in , purportedly to "streamline the experience".^[76][77]

Standards[edit]

Firefox implements many web standards, including HTML4 (almost full HTML5), XML, XHTML, MathML, SVG (full),^[78] SVG 2 (partial),^[79][80]CSS (with extensions),^[81] ECMAScript (JavaScript), DOM, XSLT, XPath, and APNG (Animated PNG) images with alpha transparency.^[82] Firefox also implements standards proposals created by the WHATWG such as client-side storage,^[83][84] and the canvas element.^[85] These standards are implemented through the Gecko layout engine, and SpiderMonkey JavaScript engine. Firefox 4 was the first release to introduce significant HTML5 and CSS3 support.

Firefox has passed the Acid2 standards-compliance test since version ^[86] Mozilla had originally stated that they did not intend for Firefox to pass the Acid3 test fully because they believed that the SVG fonts part of the test had become outdated and irrelevant, due to WOFF being agreed upon as a standard by all major browser makers.^[87] Because the SVG font tests were removed from the Acid3 test in September , Firefox 4 and greater scored /^[88][89]

Firefox also implements "Safe Browsing,"^[90] a proprietary protocol^[91] from Google used to exchange data related with phishing and malware protection.

Firefox supports the playback of video content protected by HTML5 Encrypted Media Extensions (EME), since version For security and privacy reasons, EME is implemented within a wrapper of open-source code that allows execution of a proprietaryDRM module by Adobe Systems—Adobe Primetime Content Decryption Module (CDM). CDM runs within a "sandbox" environment to limit its access to the system and provide it a randomized device ID to prevent services from 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-ins. Since version 47,^[92] "Google's Widevine CDM on Windows and Mac OS X so streaming services like Amazon Video can switch from Silverlight to encrypted HTML5 video" is also supported. Mozilla justified its partnership with Adobe and Google by stating:

Firefox downloads and enables the Adobe Primetime and Google Widevine CDMs by default to give users a smooth experience on sites that require DRM. Each CDM runs in a separate container called a sandbox and you will be notified when a CDM is in use. You can also disable each CDM and opt-out of future updates

—&#;Watch DRM content on Firefox^[93]

and that it is "an important step on Mozilla's roadmap to remove NPAPI plugin support."^[94] Upon the introduction of EME support, builds of Firefox on Windows were also introduced that exclude support for EME.^[95][96] The Free Software Foundation and Cory Doctorow condemned Mozilla's decision to support EME.^[97]

Security[edit]

See also: Browser security

Firefox allowed for a sandbox security model to manage privileges accorded to JavaScript code, but that feature has since been deprecated.^[98] It limits scripts from accessing data from other websites based on the same-origin policy.^[99] It also provides support for smart cards to web applications, for authentication purposes.^[] It uses TLS to protect communications with web servers using strong cryptography when using the HTTPS protocol.^[] The freely available HTTPS Everywhere add-on enforces HTTPS, even if a regular HTTP URL is entered. Firefox now supports HTTP/2.^[]

The Mozilla Foundation offers a "bug bounty" (US$3, to US$7, cash reward) to researchers who discover severe security holes in Firefox.^[] Official guidelines for handling security vulnerabilities discourage early disclosure of vulnerabilities so as not to give potential attackers an advantage in creating exploits.^[]

Because Firefox generally has fewer publicly known security vulnerabilities than Internet Explorer (see Comparison of web browsers), improved security is often cited as a reason to switch from Internet Explorer to Firefox.^[][][][]The Washington Post reported that exploit code for known critical security vulnerabilities in Internet Explorer was available for days in In comparison, exploit code for known, critical security vulnerabilities in Firefox was available for nine days before Mozilla issued a patch to remedy the problem.^[]

A Symantec study showed that, although Firefox had surpassed other browsers in the number of vendor-confirmed vulnerabilities that year through September, these vulnerabilities were patched far more quickly than those found in other browsers, with Firefox's vulnerabilities being fixed on average one day after the exploit code was made available, as compared to nine days for Internet Explorer.^[] Symantec later clarified their statement, saying that Firefox still had fewer security vulnerabilities than Internet Explorer, as counted by security researchers.^[]

In October , Microsoft's security engineers acknowledged that Firefox was vulnerable to a security issue found in the 'Windows Presentation Foundation' browser plug-in since February of that year. A .NET Framework SP1 Windows Update had silently installed the vulnerable plug-in into Firefox.^[] This vulnerability has since been patched by Microsoft.^[]

In , a study of the National Institute of Standards and Technology (NIST), based on data compiled from the National Vulnerability Database (NVD), Firefox was listed as the fifth-most vulnerable desktop software, with Internet Explorer as the eighth, and Google Chrome as the first.^[]

InfoWorld has cited security experts saying that, as Firefox becomes more popular, more vulnerabilities will be found,^[] a claim that Mitchell Baker, president of the Mozilla Foundation, has denied. "There is this idea that market share alone will make you have more vulnerabilities. It is not relational at all," she said.^[]

As of February&#;11, ^[update], Firefox had no known unpatched security vulnerabilities according to Secunia.^[]Internet Explorer 8 had five unpatched security vulnerabilities; the worst being rated "Less Critical" by Secunia.^[] Mozilla claims that all patched vulnerabilities of Mozilla products are publicly listed.^[]

Firefox 11, released in January , introduced a 3D page inspector that visualizes web pages' document object model three-dimensionally through WebGL. The feature was accessible from the developer tools.^[]

On January 28, , Mozilla was recognized as the most trusted internet company for privacy in ^[] This study was performed by the Ponemon Institute and was a result of a survey from more than , consumers in the United States.

In February , plans were announced for Firefox 22 to disable third-party cookies 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." Mozilla also collaborated with Stanford University's "Cookie Clearinghouse" project to develop a blacklist and whitelist of sites that will be used in the filter.^[][]

Version 23, released in August , followed the lead of its competitors by blocking 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.^[][][]

In January , TorrentFreak reported that using Firefox when connected to the internet using a VPN can be a serious security issue due to the browser's support for WebRTC.^[]

Beginning with Firefox 48, all extensions must be signed by Mozilla to be used in release and beta versions of Firefox. Firefox 43 blocked unsigned extensions but allowed enforcement of extension signing to be disabled. All extensions must be submitted to Mozilla Add-ons and be subject to code analysis in order to be signed, although extensions do not have to be listed on the service to be signed.^[][] On May 2, , Mozilla announced that it would be strengthening the signature enforcement with methods that included the retroactive disabling of old extensions now deemed to be insecure. A Firefox update on May 3 led to bug reports about all extensions being disabled. This was found to be the result of an overlooked certificate and not the policy change set to go into effect on June ^[]

In Firefox versions prior to , an information bar appears on the browser's first start asking users whether they would like to send performance statistics, or "telemetry", to Mozilla. It is enabled by default in development versions of Firefox, but not in release versions.^[] According to Mozilla's privacy policy,^[] these statistics are stored only in aggregate format, and the only personally identifiable information transmitted is the user's IP address.

In November , Firefox began using a sandbox to isolate web tabs from each other and from the rest of the system. Its lack of such a feature had previously earned it negative comparisons with Google Chrome and Microsoft Edge.^[][]

Since version 60 Firefox includes the option to use DNS over HTTPS (DoH), which causes DNS lookup requests to be sent encrypted over the HTTPS protocol. To use this feature the user must set certain preferences beginning with "eunic-brussels.eu" (Trusted Recursive Resolver) in about:config: if eunic-brussels.eu is 0, DoH is disabled; 1 activates DoH in addition to unencrypted DNS; 2 causes DoH to be used before unencrypted DNS; to use only DoH, the value must be 3. By setting eunic-brussels.eu to the URL, special Cloudflare servers will be activated.^[][] Mozilla has a privacy agreement with this server host that restricts their collection of information about incoming DNS requests.^[]

On May 21, , Firefox was updated to include the ability to block scripts that used a computer's CPU to mine cryptocurrency without a user's permission, in Firefox version The update also allowed users to block known fingerprinting scripts that track their activity across the web, however it does not resist fingerprinting on its own.^[]

On July 2, , Mozilla introduced a mechanism to allow Firefox to automatically trust OS-installed certificates to prevent TLS errors.^[]

In October , ZDNet reported Firefox version 68 ESR passed all minimum requirements for mandatory security features during an exam by the Federal Office for Information Security of Germany.^[]

In Mozilla Foundation Security Advisory –03, the company reported that the CVE vulnerability (type confusion vulnerability in IonMonkey) had been detected in the wild and was being actively exploited.^[][]

In March , Firefox launched SmartBlock in version 87 to offer protection against cross-site tracking, without breaking the websites users visit.^[] Also known as state partitioning or "total cookie protection", works via a feature in the browser that isolates data from each site visited by the user to ensure that cross-site scripting is very difficult if not impossible. The feature also isolates local storage, service workers and other common ways for sites to store data.^[]

Localizations[edit]

Notes

Firefox source code may be compiled for various operating systems; however, officially distributed binaries are provided for the following:

Microsoft Windows[edit]

Firefox was released for Windows 95, as well as Windows NT or later. Some users reported the 1.x builds were operable (but not installable) on Windows NT ^[]

The version release includes the first x64 build. It required Windows 7 or Server R2 (but those older operating system versions are no longer supported in latest Firefox versions).^[] Starting from version , Firefox for Windows requires and uses the SSE2 instruction set.

In September , Mozilla released a Metro-style version of Firefox, optimized for touchscreen use, on the "Aurora" release channel. However, on March 14, , Mozilla cancelled the project because of a lack of user adoption.^[][][]

Traditionally, installing the Windows version of Firefox entails visiting the Firefox website and downloading an installer package, depending on the desired localization and system architecture. In November , Mozilla made Firefox available on Microsoft Store. The Store-distributed package does not interfere with the traditional installation.^[][]

Most recently, Mozilla ended support for Windows 7 and 8 in Firefox , with those users being supported on the Firefox ESR branch until late

macOS[edit]

The first official release (Firefox version ) supported macOS (then called Mac OS X) on the PowerPC architecture. Mac OS X builds for the IA architecture became available via a universal binary which debuted with Firefox in

Starting with version , Firefox was released for the x64 architecture to which macOS had migrated.^[] Version also dropped support for PowerPC architecture, although other projects continued development of a PowerPC version of Firefox.^[]

Firefox was originally released for Mac OS X and higher.^[] The minimum OS then increased to Mac OS X in Firefox and in Firefox 3.^[][] Firefox 4 dropped support for Mac OS X and PowerPC Macs, and Firefox 17 dropped support for Mac OS X entirely.^[][] The system requirements were left unchanged until , when Firefox 49 dropped support for Mac OS X –^[][] Mozilla ended support for OS X – in Firefox 79, with those users being supported on the Firefox 78 ESR branch until November ^[][][] Most recently, Mozilla ended support for macOS – in Firefox , with those users being supported on the Firefox ESR branch until late

Linux[edit]

Since its inception, Firefox for Linux supported the bit memory architecture of the IA instruction set. bit builds were introduced in the release.^[] The release replaced GTK with as a system requirement on Linux and other systems running eunic-brussels.eu^[] Starting with , the bit builds require the SSE2 instruction set. Firefox also can run on number of other architectures on Linux, including ARM, AArch64, POWER/PowerPC/Power ISA, SPARC, PA-RISC, MIPS, s, and in the past Alpha, IA (Intel Itanium) and m68k.

Firefox for Android[edit]

Main article: Firefox for Android

Firefox for mobile, code-named "Fennec", was first released for Maemo in January with version ^[] and for Android in March with version ^[] Support for Maemo was discontinued after version 7, released in September ^[] Fennec had a user interface optimized for phones 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 Firefox Sync.^[] It was criticized for being slow,^[] however, in part due to its poor port of Gecko.^[] At the end of its existence, it had a market share of % on Android.^[]

In August , Mozilla launched a new version of its Firefox for Android app, named Firefox Daylight to the public^[] and codenamed Fenix,^[] after a little over a year of testing.^[] It boasted higher speeds with its new GeckoView engine, which is described as being "the only independent web engine browser available on Android". It also added Enhanced Tracking Protection , a feature that blocks many known trackers on the Internet.^[] It also added the ability to place the address bar on the bottom, and a new Collections feature.^[] However, it was criticized for only having nine Add-ons at launch, and missing certain features.^[][][] In response, Mozilla stated that they will allow more Add-ons with time.^[]
