Mozilla Firefox is a free, open source web browser developed by the Mozilla Foundation. The software is licensed under the Mozilla Public License version 2.0. As the second most popular web browser in the world, it is the main competitor of Google Chrome.
In 2017, Mozilla's Project Quantum developed a new browser engine. A developer edition of the browser with this new engine was released in September 2017 with a general release taking place two months later. This new engine is at least twice as fast as the old gecko engine, and still uses less system memory that Chromium.
Mozilla Firefox is a fast, stable browser with plenty of options. It is continually being updated, patched and improved. It can also be customized with a variety of addons from Mozilla's library. Third party plugins may also be added to the browser. Firefox has also been showing an interest in security lately. They have been making security-motivated changes, some of which are not found in Chromium and other competitors.
With the development of the new "quantum" engine, this browser has apparently improved its performance significantly.
When compared to Chromium, this browser has historically failed to perform quite as quickly. However, the new engine has helped to eliminate this deficiency. Although addons are plentiful and easy to create, they must be frequently updated, or the browser will disable them. Additionally, Mozilla has taken a very liberal political stance, which some find hard to agree with. For these reasons, some opt for forks of Firefox.
Firefox was originally developed as an offshoot of the Mozilla Browser project, developed by Netscape, as a lightweight version of the software. The original Mozilla browser was extremely feature rich, including such things as an HTML editor, which created a large and correspondingly slow piece of software. Firefox has gone through several name changes, all due to existing trademarks. It was originally named Phoenix, then Firebird and finally Firefox.
Since its original release in 2002, Firefox had a continued increase in the market share of web browsers until 2009, then a small decline due to competition from Google Chrome. Exact numbers are difficult to determine, but as of November 2012 worldwide, Firefox had a 24% share, and as of November 2012, 28.5% in Europe. By spring 2016, however, the browser's market share had dropped off to just over 15%. Through heavy advertising and promotion, Google has continued to take market share from Mozilla and other competitors.
The browser is officially supported in over 70 languages, and is available for the different versions of Microsoft Windows, Apple Mac OS X, and Linux operating systems. Unofficial builds are available for Sun Microsystems Solaris, BSD, and other operating systems.
Political Stance and boycotts of the Mozilla browser
Boycotts of the Mozilla browser
Some conservatives/libertarians are encouraging people to uninstall Firefox and instead use open-source web browsers based on Mozilla Firefox or use other browser alternatives. For example, Vox Day is encourage people to migrate to the Pale Moon browser which is based on the Mozilla Firefox browser and Dennis Prager encouraged people to uninstall Firefox.
There are other browsers based on Firefox such as the Comodo IceDragon browser and the Waterfox browser (which is reportedly faster than the Firefox browser). The "Brave" web browser is also reportedly faster than the Firefox browser by about 27% (although this report may be have become obsolete with Mozilla's release of Quantum).
