Software description

Mozilla Firefox Quantum is a free and open sourced internet browser that was developed by the Mozilla Foundation and its sister company, Mozilla Corporation. Mozilla Firefox, also known as Firefox began incorporating brand new technology using their Gecko layout engine to render web pages to a more current web standard, in 2017.

The Mozilla Corporation first introduced Firefox under a code name of “Phoenix” in 2002 for users that required a standalone browser in comparison to the Mozilla application bundles that were available at the time. It was during its initial Beta phase that Firefox was proven to be popular with testers. It was applauded for the speed of the browser, security features and additional add-ons in comparison to Microsoft’s Internet Explorer (version 6 was active at the time).

When Firefox was released in 2004 it was noted to have had 60 million + downloads within a nine-month period. It succeeded Netscape Navigator as the main browser for Mozilla. Mozilla was originally created by Netscape in 1998 before they were bought over by the company, AOL.

Firefox promotes a more innate user interface and is available on Windows 7 and above, macOS, Linux and unofficially for Unix and Unix like operating systems. On its release it overtook internet Explorer and still has over 50% of desktop downloads to date.


Mozilla Firefox ensures the implementation of a lot of web standards which includes HTML 4, HTML 5, XML, XHTML, MathML, SV2, CSS with additional extensions, ECMAScript (also known as JavaScript), XSLT, DOM, XPath, APNG (which is known as Animated PNG). There is also further web standard implementation created by WHATWG which includes client-side storages and canvas elements, this is done via Gecko Layout Enginer and SpiderMonkey which is a JavaScript Engine.
