Firefox uses the Gecko layout engine to render web pages, which implements current and anticipated web standards.

Mozilla Firefox Quantum Code Name Quantum

In 2017, Firefox began incorporating new technology under the code name Quantum to promote parallelism and a more intuitive user interface.

Firefox is officially available for Windows 7 or newer, macOS, and Linux.

Its unofficial ports are available for various Unix and Unix-like operating systems including FreeBSD, 9 OpenBSD, 10 NetBSD, 11 illumos, 12 and Solaris Unix.

Firefox is also available for Android and iOS.

However, the iOS version uses the WebKit layout engine instead of Gecko due to platform limitations, as with all other iOS web browsers.

An optimized version of Firefox is also available on the Amazon Fire TV, as one of the two main browsers available with Amazons Silk Browser.

During its beta phase, Firefox 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.

Firefox was released on November 9, 2004, 28 and challenged Internet Explorer s dominance with 60 million downloads within nine months.

Firefox is the spiritual successor of Netscape Navigator, as the Mozilla community was created by Netscape in 1998 before their acquisition by AOL.

Although all countries except for two have Google Chrome as their mainly used (desktop) web browser, the exceptions are in Cuba where Firefox still has over 50 desktop usage, and in Eritrea (most used at 40.87).

Firefox also has over 40 usage in Armenia, and over 20 usage in Germany, Austria, Poland, Luxembourg, Iran, Myanmar, East Timor, Burkina Faso, Madagascar, Cameroon, Ethiopia, Mali, Togo, and Uganda.

They believed the commercial requirements of Netscape s sponsorship and developer-driven feature creep compromised the utility of the Mozilla browser.

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.

Version 0.1 was released on September 23, 2002.

On April 3, 2003, the Mozilla Organization announced that they planned to change their focus from the Mozilla Suite to Firefox and Thunderbird.

Phoenix was renamed due to a trademark claim from Phoenix Technologies.

The replacement name, Firebird, provoked an intense response from the Firebird database software project.

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, 2004.

The name Firefox was said to be derived from a nickname of the red panda, 45 which became the mascot for the newly named project.

For the abbreviation of Firefox, Mozilla prefers Fx or fx, though it is often abbreviated as FF.

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 2017, 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 1.0.

Firefox Hello was an implementation of WebRTC, added in October 2014, 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 2016.

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.

Firefox previously supported add-ons using the XUL and XPCOM APIs, which allowed them to directly access and manipulate much of the browsers 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 and newer.

The Firefox add-on website also gives users the ability to add other applications such as games, ad-blockers, screenshot apps, and many other apps.

Firefox 4 was first biggest release towards supporting HTML5 and CSS3.

For security and privacy reasons, which EME is implemented within a wrapper of open-source code that allows execution of a proprietary DRM 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.
