MOZILLA

Mozilla Firefox is a free and open source web browser descended from the Mozilla Application Suite, managed by the Mozilla Corporation. Firefox had 19.46% of the recorded usage share of web browsers as of September 2008, making it the second-most popular browser in current use worldwide, after Internet Explorer.

To display web pages, Firefox uses the Gecko layout engine, which implements some current web standards plus a few features which are intended to anticipate likely additions to the standards.

Firefox includes tabbed browsing, a spell checker, incremental find, live bookmarking, a download manager, and an integrated search system that uses the user's desired search engine. Functions can be added through add-ons created by third-party developers,[4] the most popular of which include the NoScript JavaScript disabling utility, Tab Mix Plus customizer, FoxyTunes media player control toolbar, Adblock Plus ad blocking utility, StumbleUpon (website discovery), DownThemAll! download enhancer and Web Developer toolbar.

Firefox runs on various versions of Microsoft Windows, Mac OS X, Linux, and many other Unix-like operating systems.


HISTORY:
Dave Hyatt and Blake Ross began working on the Firefox project as an experimental branch of the Mozilla project. They believed the commercial requirements of Netscape's sponsorship and developer-driven feature creep compromised the utility of the Mozilla browser.[8] To combat what they saw as the Mozilla Suite's software bloat, they created a stand-alone browser, with which they intended to replace the Mozilla Suite. On April 3, 2003, the Mozilla Organization announced that they planned to change their focus from the Mozilla Suite to Firefox and Thunderbird.

The Firefox project has undergone several name changes. Originally titled Phoenix, it was renamed because of trademark issues with Phoenix Technologies. The replacement name, Firebird, provoked an intense response from the Firebird free database software project.In response, the Mozilla Foundation stated that the browser should always bear the name Mozilla Firebird to avoid confusion with the database software. Continuing pressure from the database server's development community forced another change; on February 9, 2004, Mozilla Firebird became Mozilla Firefox,[13] often referred to as simply Firefox. Mozilla prefers Firefox to be abbreviated as Fx or fx, though it is often abbreviated as FF.[14]

The Firefox project went through many versions before 1.0 was released on November 9, 2004. After a series of stability and security fixes, the Mozilla Foundation released its first major update, Firefox version 1.5, on November 29, 2005. On October 24, 2006, Mozilla released Firefox 2. This version includes updates to the tabbed browsing environment, the extensions manager, the GUI, and the find, search and software update engines; a new session restore feature; inline spell checking; and an anti-phishing feature which was implemented by Google as an extension,[15][16] and later merged into the program itself.In December 2007, Firefox Live Chat was launched. It allows users to ask volunteers questions through a system powered by Jive Software, with guaranteed hours of operation and the possibility of help after hours.


version 3:
Mozilla Firefox 3 was released on June 17, 2008 by the Mozilla Corporation. Firefox 3 uses version 1.9 of the Mozilla Gecko layout engine for displaying web pages. The new version fixes many bugs, improves standard compliance, and implements new web APIs.Other new features include a redesigned download manager, a new "Places" system for storing bookmarks and history, and separate themes for different operating systems.

Development stretches back to the first Firefox 3 beta (under the codename 'Gran Paradiso') which had been released several months earlier on 19 November 2007,and was followed by several more beta releases in spring 2008 culminating in the June release.

Firefox 3 had 2.31% of the recorded usage share of web browsers by June 2008, and had over 8 million unique downloads the day it was released, setting a Guinness World Record.



features:
Features included with Firefox are tabbed browsing, spell checker, incremental find, live bookmarking, an integrated download manager, keyboard shortcuts, 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 addons.mozilla.org with nearly 6000 add-ons in it as of September 2008.

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.
