FeaturesFeatures included with Firefox are tabbed browsing, spell checker, incremental find, live bookmarking, an integrated download manager, and an integrated search system that uses the user's desired search engine. The developers of Firefox aimed to produce a browser that "just surfs the web" and delivers the "best possible browsing experience to the widest possible set of people."
Users can customize Firefox with extensions and themes. Mozilla maintains an add-on repository at [https://addons.mozilla.org/en-US/firefox/ addons.mozilla.org] with nearly 2000 add-ons in it as of September 2007.
Firefox provides an environment for web developers in which they can use built-in tools, such as the Error Console or the DOM Inspector, or extensions, such as Firebug.
Standards supportMozilla Firefox supports many web standards, including HTML, XML, XHTML, SVG 1.1 (partial), CSS (with extensions), ECMAScript, DOM, MathML, DTD, XSLT, XPath, and PNG images with alpha transparency. Firefox also supports standards proposals created by the WHATWG such as client-side storage, and canvas element.
Firefox passes the Acid2 standards-compliance test from version 3.0. Firefox 3.0 does not pass the Acid3 test; it scores 71/100 and does not render the image correctly.
Version 3.0
Licensing Firefox is free and open source software, and is tri-licensed under the Mozilla Public License (MPL), GNU General Public License (GPL), and the GNU Lesser General Public License (LGPL). These licenses permit 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, and Songbird make use of code from Firefox
The official end-user builds of Firefox distributed from mozilla.com are licensed under the Mozilla End User License Agreement. Several elements do not fall under the scope of the tri-license and have their use restricted by the EULA, including the trademarked Firefox name, the proprietary artwork, and the proprietary closed-source Talkback crash reporter. Because of this and the clickwrap agreement included in the Windows version, the Free Software Foundation (FSF) consider these builds proprietary software. However, BreakPad, an open source crash reporting system, has replaced Talkback in Firefox 3.0.
In the past, Firefox was licensed solely under the MPL, which the FSF criticizes for being weak copyleft; the license permits, in limited ways, proprietary derivative works. Additionally, code under the MPL cannot legally be linked with code under the GPL or the LGPL. To address these concerns, Mozilla re-licensed Firefox under the tri-license scheme of MPL, GPL, and LGPL. Since the re-licensing, developers have been free to choose the license under which they will receive 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 choose the MPL.
Trademark and logo issues 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.
There has been some controversy over the Mozilla Foundation's intentions in stopping certain open source distributions from using the "Firefox" trademark. Former Mozilla CEO 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".
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 work unencumbered by restrictions on the Firefox trademark (this is also often used for betas and 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. The name "Deer Park" is used for derivatives of Firefox 1.5, "Bon Echo" for derivatives of Firefox 2.0, and "Gran Paradiso" is used for derivatives of Firefox 3.0. The codename Minefield and a modified version of the generic logo stylized to look like a bomb is used for unofficial build of version 3.0 and later, and for nightly builds of the trunk.
Outside of certain exceptions made for "community editions", 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 of copyright restrictions on its use incompatible with the project's guidelines), they were told by a representative of the Mozilla Foundation that this was not acceptable, and were asked to either 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.
AdvertisingThe 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. The portal enhanced the "Get Firefox" button 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 is an attempt to break the world download record with the release of Firefox 3. The idea is to have the newest version downloaded by as many people as possible within a 24 hour time period.
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.
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.

Mozilla Firefox's market share has grown for each growth period since inception, mostly at the expense of Internet Explorer. Internet Explorer has seen a steady decline of its usage share since Firefox's release. By early 2008, Firefox had approximately 15% global usage share of web browsers. Market shares break down as following: 43% for Internet Explorer 7, 32% for Internet Explorer 6, 16% for Firefox 2.0, 4% for Safari 3.0, and less than half a percent for both Firefox 1.x and Internet Explorer 5.x versions.
As one article noted after the release of Firefox 2.0 in October 2006, "IE6 had the lion's share of the browser market with 77.22%. Internet Explorer 7 had climbed to 3.18%, while Firefox 2.0 was at 0.69%."
A Softpedia article, however, noted in July 2007 that "Firefox 2.0 has been also expanding its share constantly in spite of IE7. From just 0.69% in October 2006, Firefox 2.0 is now accounting for 11.07% of the market. Mozilla has even sacrificed version 1.5 of its open source browser for Firefox 2.0. With support cut at the end of June, Firefox 1.5 dropped to just 2.85%."
Downloads have continued at an increasing rate since Firefox 1.0 was released in November 2004, and as of February 21, 2008 Firefox has been downloaded over 500 million times. This number does not include downloads using software updates or those from third-party websites. They do not represent a user count, as one download may be installed on many machines, one person may download the software multiple times, or the software may be obtained from a third party. According to Mozilla CEO John Lilly, Firefox had about 140 million users as of February 2008.
Critical reactionForbes.com called Firefox the best browser in a 2004 commentary piece. PC World named Firefox "Product of the Year" in 2005 on their "100 Best Products of 2005" list. After the release of Firefox 2 and Internet Explorer 7 in 2006, PC World reviewed both and declared that Firefox was the better browser. Which? Magazine named Firefox its "Best Buy" web browser..
Like other browsers, Firefox has had a number of vulnerabilities that have affected its security, although according to , not as many as Internet Explorer.
Relationship with GoogleThe Mozilla Corporation's relationship with Google has been noted in the media, especially with regard to their paid referral agreement. The release of the anti-phishing protection in Firefox 2 in particular raised considerable controversy: anti-phishing protection enabled by default is based on a list updated by twice-hourly downloads to the user's computer from Google's server. The user cannot change the data provider within the GUI, and is not informed who the default data provider is. The browser also sends Google's cookie with each update request. An additional, explicitly opt-in security feature has been added to recent builds by the Mozilla Foundation. This anti-phishing feature provides live protection by checking each visited URL with Google. Some Internet privacy advocacy groups have expressed concerns surrounding Google's possible uses of this data, though Firefox's privacy policy states that Google may not use personal information for any purposes other than the anti-phishing protection feature.
In 2005, the Mozilla Foundation and Mozilla Corporation had a combined revenue of US$52.9 million, with approximately 95 percent derived from search engine royalties. In 2006, the Mozilla Foundation and Mozilla Corporation had a combined revenue of US$66.9 million, with approximately 90 percent derived from search engine royalties.
Response from MicrosoftMicrosoft's head of Australian operations, Steve Vamos, stated in late 2004 that he did not see Firefox as a threat and that there was not significant demand for the feature set of Firefox among Microsoft's users. Microsoft Chairman Bill Gates has used Firefox, but he has commented "so much software gets downloaded all the time, but do people actually use it?"
A Microsoft SEC filing on June 30, 2005 acknowledged that "competitors such as Mozilla offer software that competes with the Internet Explorer Web browsing capabilities of our Windows operating system products." The release of Internet Explorer 7 was fast tracked, and included functionality that was previously available in Firefox and other browsers, such as tabbed browsing and RSS feeds.
Despite the cold reception from Microsoft's top management, the Internet Explorer development team maintains a relationship with Mozilla. They meet regularly to discuss web standards such as extended validation certificates. In 2005 Mozilla agreed to allow Microsoft to use its Web feed logo in the interest of common graphical representation of the Web feeds feature.
In August 2006, Microsoft offered to help Mozilla integrate Firefox with the then-forthcoming Windows Vista, which Mozilla accepted.
In October 2006, as congratulations for a successful ship of Firefox 2, the Internet Explorer 7 development team sent a cake to Mozilla. As a nod to the browser wars, some readers joked about the cake being poisoned, while others jokingly suggested that Mozilla sent a cake back along with the recipe, in reference to the open-source software movement. The IE development team sent another cake on June 17, 2008, upon the successful release of Firefox 3.
In November 2007, Microsoft employee Jeff Jones 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 Microsoft's bundling of security fixes and the study's focus on fixes, rather than vulnerabilities, as crucial flaws.
Future developments The precursory releases of upcoming Firefox releases are codenamed "", as this is the name of the trunk builds. Development of Firefox after version 3.0 is split over two milestones: version 3.1 and version 4.0. Firefox 3.0, formerly in the development stage, was released to the general public on June 17, 2008. Development for the 3.1 releases takes place on the Mozilla trunk, with releases and pre-release nightly builds coming from the Mozilla 1.8.1 branch (2.0) and the (3.0). Development for 4.0 will be based on Mozilla 2.
Version 3.1Version 3.1, codenamed Shiretoko, is planned to include support for the |
