Updated: 05/21/2018 by Computer Hope

The Mozilla Firefox logo.The Firefox web browser was first released in beta on September 23, 2002, as the "Mozilla Browser," although it was internally code-named "Phoenix." Firefox 1.0 was officially released on November 9, 2004.

Firefox became a popular alternative to Microsoft Internet Explorer 6.0 when users sought a browser that could better protect them from spyware and malicious websites. As of 2017, it is the fourth-most popular browser after Google Chrome, Apple Safari, and UC Browser.

Features

Firefox features tabbed browsing with individual processes per tab, popup blocking, private browsing, phishing detection, and a sandbox security model.

Firefox Quantum

On November 14, 2017, Mozilla announced Firefox Quantum, a new technology base for the Firefox browser. Every new version of Firefox for desktop computers uses Firefox Quantum technology, beginning with version 57. Mobile versions use the new appearance features (code-named "Photon UI"), but not the underlying technology.

Firefox Quantum is roughly twice as fast as previous versions of Firefox and uses less RAM when browsing. Large portions of Firefox Quantum were re-written using Mozilla's home-grown system programming language, Rust, which provides enhanced thread safety. As a result, Firefox takes greater advantage of multiprocessing capabilities on the user's computer.
