Firefox 4 Licensing Firefox source code is free software, with most of it being released under the Mozilla Public License (MPL). This license permits anyone to view, modify, and/or redistribute the source code, and several publicly released applications have been built on it; for example, Netscape, Flock, Miro, Iceweasel, and Songbird make use of code from Firefox. In the past, Firefox was licensed solely under the MPL, which the FSF (Free Software Foundation) criticized for being weak copyleft; the license permitted, in limited ways, proprietary derivative works. Additionally, code only licensed under the MPL could not legally be linked with code under the GPL. To address these concerns, Mozilla re-licensed most of Firefox under the tri-license scheme of MPL, GPL, or LGPL. Since the re-licensing, developers were free to choose the license under which they received most of the code, to suit their intended use: GPL or LGPL linking and derivative works when one of those licenses is chosen, or MPL use (including the possibility of proprietary derivative works) if they chose the MPL. However, on January 3, 2012, Mozilla released the GPL-compatible MPL 2.0, and with the release of Firefox 13 on June 5, 2012, Mozilla used it to replace the tri-licensing scheme. Trademark and logo The name "Mozilla Firefox" is a registered trademark; along with the official Firefox logo, it may only be used under certain terms and conditions. Anyone may redistribute the official binaries in unmodified form and use the Firefox name and branding for such distribution, but restrictions are placed on distributions which modify the underlying source code. The name "Firefox" derives from a nickname of the red panda. Mozilla has placed the Firefox logo files under open-source licenses, but its trademark guidelines do not allow displaying altered or similar logos in contexts where trademark law applies. There has been some controversy over the Mozilla Foundations intentions in stopping certain open source distributions from using the "Firefox" trademark. 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 Foundations only concern was with users getting a consistent experience when they used "Firefox". To allow distributions of the code without using the official branding, the Firefox source code contains a "branding switch". This switch allows the code to be compiled without the official logo and name, for example to produce a derivative Logo used for Iceweasel work unencumbered by restrictions on the Firefox trademark (this is also often used for alphas of future Firefox versions). In the unbranded compilation 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. Distributing modified versions of Firefox under the "Firefox" name requires explicit approval from Mozilla for the changes made to the underlying code, and requires the use of all of the official branding. For example, it is 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 Mozillas copyright restrictions at the time were incompatible with Debians guidelines), they were told by a representative of the Mozilla Foundation that this was not acceptable, and were asked either to comply with the published trademark guidelines or cease using the "Firefox" name in their distribution. Ultimately, Debian switched to branding their modified version of Firefox "Iceweasel", along with other Mozilla software.
Firefox 5 Branding and visual identity Early Firebird and Phoenix releases of Firefox were considered to have had reasonable visual designs, but were not up to the same standards as many professionally released software packages. In October 2003, professional interface designer Steven Garrity wrote an article covering everything he considered to be wrong with Mozillas visual identity. The page received a great deal of attention; the majority of criticism leveled at the article fell along the lines of "wheres the patch?" Shortly afterwards, Garrity was invited by the Mozilla Foundation 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, including new icon designs by silverorange, a group of web developers with a long-standing relationship with Mozilla, with final renderings by Jon Hicks, who had previously worked on Camino. The logo was later revised and updated, fixing several flaws found when it was enlarged. The animal shown in the logo is a stylized fox, although "firefox" is considered to be a common name for the red panda. The panda, according to Hicks, "didnt really Blue globe artwork is distributed with Firefox source code, and is conjure up the right imagery" and wasnt widely known. The logo was chosen explicitly not protected as a to make an impression while not shouting out with overdone artwork. It had to trademark  stand out in the users mind, be easy for others to remember, and stand out without causing too much distraction when seen among other icons. The Firefox icon is a trademark used to designate the official Mozilla build of the Firefox software and builds of official distribution partners. For this reason, Debian and other software distributors who distribute patched or modified versions of Firefox do not use the icon. The crash reporting service was initially closed source, but switched with version 3 from a program called Talkback to the open source BreakPad & Socorro . Other logos are also used for specific versions of the software or its derivatives: The current Aurora logo The current "nightly" logo Minefield logo (former name for (alpha/pre-beta) (experimental/pre-alpha) "nightly" Firefox) Promotion The rapid adoption of Firefox, 100 million downloads in its first year of availability, followed a series of aggressive marketing campaigns starting in 2004 with a series of events Blake Ross and Asa Dotzler called "marketing weeks". On September 12, 2004, a marketing portal dubbed "Spread Firefox" (SFX) debuted along with the Firefox Preview Release, creating a centralized space for the discussion of various marketing techniques. A two-page ad in the December 16 edition of the New York Times, placed by Mozilla Foundation in coordination with Spread Firefox, featured the names of the thousands of people worldwide who contributed to the Mozilla Foundations fundraising campaign to support the launch of the Firefox 1.0 web browser. SFX portal enhanced the "Get Firefox" button
Firefox 6 program, giving users "referrer points" as an incentive. The site lists the top 250 referrers. From time to time, the SFX team or SFX members launch marketing events organized at the Spread Firefox website. As a part of the Spread Firefox campaign, there was an attempt to break the world download record with the release of Firefox 3. The "World Firefox Day" campaign started on July 15, 2006, the third anniversary of the founding of the Mozilla Foundation, and ran until September 15, 2006. Participants registered themselves and a friend on the website for nomination to have their names displayed on the Firefox Friends Wall, a digital wall that will be displayed at the headquarters of the Mozilla Foundation. In December 2007, Mozilla launched Live Chat , a service allowing users to seek technical support from volunteers. Because Live chat is kept running by volunteers, it is only available when they are online. On February 21, 2008 in honor of reaching 500 million downloads, the Firefox community celebrated by visiting FreeRice to earn 500 million grains of rice. Some of Firefoxs contributors made a crop circle of the Firefox logo in an oat field near Amity, Oregon, near the intersection of Lafayette Highway and Walnut Hill Road. In February 2011, Mozilla announced that it would be retiring Spread Firefox (SFX). Three months later, in May 2011, Mozilla officially closed Spread Firefox. Mozilla wrote that "there are currently plans to create a new iteration of this website [Spread Firefox] at a later date." Reception Most used web browser by country according to StatCounter.

In 2008, CNET compared Safari, Chrome, Firefox, and Internet Explorer in their "Battle of the Browsers" in terms of performance, security, and features, where Firefox was selected as a favorite. In February 2012, Toms Hardware compared Safari 5.1.2, Google Chrome 17, Mozilla Firefox 10, Opera 11.61 and Microsoft Internet Explorer 9 on both Ubuntu 11.10 and Windows 7 OS (Internet Explorer & Safari excluded from Ubuntu because of OS availability) in a "Web Browser Grand Usage share of web browsers (March 2012 – StatCounter) Prix". They concluded, that based on performance, Chrome 17 was selected as their favorite on the Ubuntu OS – but they also concluded that on Windows OS, Firefox 10 was their favorite. Performance In December 2005, Internet Week ran an article in which many readers reported high memory usage in Firefox 1.5. Mozilla developers said that the higher memory use of Firefox 1.5 was at least partially due to the new fast backwards-and-forwards (FastBack) feature. Other known causes of memory problems were malfunctioning extensions such as Google Toolbar and some older versions of Adblock, or plug-ins, such as older versions of Adobe Acrobat Reader. When PC Magazine compared memory usage of Firefox 2, Opera 9, and Usage share of web browsers according to Internet Explorer 7, they found that Firefox used approximately as StatCounter. much memory as the other two browsers. Softpedia noted that Firefox 1.5 took longer to start up than other  browsers, which was confirmed by further speed tests. IE 6 launched more swiftly than Firefox 1.5 on Windows XP since many of its components were built into the OS and loaded during system startup. As a

Firefox 18 • Improve display of location bar results • Silent Update: Updated workflow for users with incompatible add-ons Platform support Mozilla provides development builds of Firefox in the following channels: "Beta", "Aurora", and "Nightly". As of July 2012, Firefox 15 beta is in the "Beta" channel, Firefox 16 alpha is in the "Aurora" channel, and Firefox 17 pre-alpha is in the "Nightly" channel. Features planned for future versions include silent updating so that version increments will not bother the user, although the user will be able to disable that function. A different looking user-interface called "Australis" is also planned. Firefox for mobile Firefox for mobile, codenamed Fennec, is a web browser for smaller non-PC devices, mobile phones and PDAs. It was first released for the Nokia Maemo operating system (specifically the Nokia N900) on January 28, 2010. Version 4 for Android and Maemo was released on March 29, 2011. The browsers version number was bumped from version 2 to version 4 to synchronize with all future desktop releases of Firefox since the rendering engines used in both browsers are the same. Version 7 was the last release for Maemo on the N900. The user interface is completely redesigned and optimized for small screens, the controls are hidden away so that only the web content is shown on screen, and it uses touchscreen interaction methods. It includes the Awesomebar, tabbed browsing, Add-on support, password manager, location-aware browsing, and the ability to synchronize with the users computer Firefox browser using Firefox Sync. Firefox ESR Firefox for mobile 14.0 on Android Firefox ESR is a version of Firefox for organizations and other adopters who need extended support for mass deployments. Unlike the regular ("rapid") releases, the ESR will be updated with new features and performance enhancements annually, receiving regular security updates during the year. 64-bit support Operating System 64-bit support Windows No Mac OS X Yes Linux Yes 64-bit support for Firefox is inconsistent across operating systems. 64-bit is supported by Mozilla in Mac OS X and Linux, but there are no official 64-bit releases for Windows OS. Mozilla does provide a 64-bit version for their Firefox nightly builds, but they are considered unstable by Mozilla. The official releases of Firefox for Mac OS X are universal builds that include both 32-bit and 64-bit versions of the browser in one package, and have been this way since Firefox 4. A typical browsing session uses a combination of the 64-bit browser process and a 32-bit plugin process, because some popular plugins still are 32-bit.
Firefox 19 Mozilla made Firefox for Linux 64-bit a priority with the release of Firefox 4, labeling it as tier 1 priority. Since being labeled tier 1, Mozilla has been providing official 64-bit releases for its browser for the Linux OS. Vendor-backed 64-bit support has existed for Linux based OSs such as Novell-Suse Linux, Red Hat Enterprise Linux, and Ubuntu prior to Mozillas support of 64-bit, even though vendors were faced with the challenge of having to turn off the 64-bit JIT compiler due to its instability prior to Firefox 4. System requirements Browsers compiled from Firefox source code may run on various operating systems; however, officially distributed binaries are meant for the following: Microsoft Windows (XP SP2/SP3, Server 2003, Vista or 7), Mac OS X 10.5, Mac OS X 10.6 and Linux (with the following libraries installed: GTK+ 2.10 or higher, GLib 2.12 or higher, Pango 1.14 or higher, X.Org 1.0 or higher (1.7 or higher is recommended), libstdc++ 4.3 or higher).

Firefox 21 In November 2007, Jeff Jones (a "security strategy director" in Microsofts Trustworthy Computing Group) criticized Firefox, claiming that Internet Explorer experienced fewer vulnerabilities and fewer higher severity vulnerabilities than Firefox in typical enterprise scenarios. Mozilla developer Mike Shaver discounted the study, citing Microsofts bundling of security fixes and the studys focus on fixes, rather than vulnerabilities, as crucial flaws. In February 2009, Microsoft released Service Pack 1 for version 3.5 of the .NET Framework. This update also installed Microsoft .NET Framework Assistant add-on (enabling ClickOnce support). The update received media attention after users discovered that the add-on could not be uninstalled through the add-ons interface. Several hours after the website Annoyances.org posted an article regarding this update, Microsoft employee Brad Abrams posted in his blog Microsofts explanation for why the add-on was installed, and also included detailed instructions on how to remove it. However, the only way to get rid of this extension was to modify manually the Windows Registry, which could cause Windows systems to fail to boot up if not done correctly. On October 16, 2009, Mozilla blocked all versions of Microsoft .NET Framework Assistant from being used with Firefox and from the Mozilla Add-ons service. Two days later, the add-on was removed from the blocklist after confirmation from Microsoft that it is not a vector for vulnerabilities. Version 1.1 (released on June 10, 2009 to the Mozilla Add-ons service) and later of the Microsoft .NET Framework Assistant allows the user to disable and uninstall in the normal fashion. Firefox was one of the twelve browsers offered to European Economic Area users of Microsoft Windows in 2010 – see BrowserChoice.eu.
