Mozilla Firefox or simply Firefox, is a free and open-source web browser developed by the Mozilla Foundation and its subsidiary, the Mozilla Corporation. Firefox uses the Gecko rendering engine to display web pages. In 2017, Firefox began incorporating new technology under the code name Quantum to promote parallelism and a more intuitive user interface. Firefox is available for Windows 7 or Windows 10, macOS, and Linux. Its unofficial ports are available for various Unix and Unix-like operating systems including FreeBSD, OpenBSD, NetBSD, illumos, 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 requirements, 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 Amazon's Silk Browser.
Mozilla Thunderbird is a free and open-source cross-platform email client, personal information manager, news client, RSS and chat client developed by the Mozilla Foundation. The project strategy was originally modeled after that of Mozilla's Firefox web browser.
A browser war is competition for dominance in the usage share of web browsers. The "First Browser War" during the late 1990s pitted Microsoft's Internet Explorer against Netscape's Navigator. Browser wars continued with the decline of Internet Explorer's market share and the popularity of other browsers including Firefox, Google Chrome, Safari, Microsoft Edge and Opera.
Conkeror is a Mozilla-based web browser designed to be navigated primarily by a computer keyboard. Its design is mainly patterned after the text editor GNU Emacs, with some influence from other programs, including vi.

Greasemonkey is a userscript manager made available as a Mozilla Firefox extension. It enables users to install scripts that make on-the-fly changes to web page content after or before the page is loaded in the browser.
The Mozilla Application Suite is a discontinued cross-platform integrated Internet suite. Its development was initiated by Netscape Communications Corporation, before their acquisition by AOL.

Tab Mix Plus was a Mozilla Firefox extension that adds to the tabbed browsing functions in Firefox. It was a popular extension on Mozilla Add-ons, which records download statistics. TMP is a collection of features from other extensions built in one package. Lifehacker named it one of their "Top 10 must-have Firefox extensions" for 2009. PC World said that "With Tab Mix Plus, Firefox tabs go past the obvious and into the indispensable... it's hard to imagine how you lived without it." As the only extension providing multi-row tab support, Wired and CNET both called it a "must-have" that is "powerful" and "gives you what feels like an infinite amount of control over tab behaviour."
In the context of the World Wide Web, a bookmark is a Uniform Resource Identifier (URI) that is stored for later retrieval in any of various storage formats. All modern web browsers include bookmark features. Bookmarks are called favorites or Internet shortcuts in Internet Explorer, and by virtue of that browser's large market share, these terms have been synonymous with bookmark since the first browser war. Bookmarks are normally accessed through a menu in the user's web browser, and folders are commonly used for organization. In addition to bookmarking methods within most browsers, many external applications offer bookmark management.
A browser toolbar is a toolbar that resides within a browser's window. All major web browsers provide support to browser toolbar development as a way to extend the browser's GUI and functionality. Browser toolbars are considered to be a particular kind of browser extensions that present a toolbar. Browser toolbars are specific to each browser, which means that a toolbar working on a browser does not work on another one. All browser toolbars must be installed in the corresponding browser before they can be used, and require updates when new versions are released.
iMacros is a browser based application for macro recording, editing and playback for web automation and testing. It is provided as a standalone application and extensions for the Mozilla Firefox, Google Chrome, and Internet Explorer web browsers.

Demo macros and JavaScript code examples are included with the software. Running strictly JavaScript based macros were removed in later versions of iMacros browser extensions. However, users can use alternative browser like Pale Moon, based on older version of Mozilla Firefox to use JavaScript files for web based automated testing with Moon Tester Tool.

Content Security Policy (CSP) is a computer security standard introduced to prevent cross-site scripting (XSS), clickjacking and other code injection attacks resulting from execution of malicious content in the trusted web page context. It is a Candidate Recommendation of the W3C working group on Web Application Security, widely supported by modern web browsers. CSP provides a standard method for website owners to declare approved origins of content that browsers should be allowed to load on that website—covered types are JavaScript, CSS, HTML frames, web workers, fonts, images, embeddable objects such as Java applets, ActiveX, audio and video files, and other HTML5 features.
Firefox was created by Dave Hyatt and Blake Ross as an experimental branch of the Mozilla browser, first released as Firefox 1.0 on November 9, 2004. Starting with version 5.0, a rapid release cycle was put into effect, resulting in a new major version release every six weeks. This was gradually accelerated further in late 2019, so that new major releases occur on four-week cycles starting in 2020. Firefox 90 is the latest version, which was released on July 13, 2021.
Browser security is the application of Internet security to web browsers in order to protect networked data and computer systems from breaches of privacy or malware. Security exploits of browsers often use JavaScript, sometimes with cross-site scripting (XSS) with a secondary payload using Adobe Flash. Security exploits can also take advantage of vulnerabilities that are commonly exploited in all browsers.
