About Mozilla Firefox

The Mozilla Corporation & its subsidiary, the Mozilla Corporation, developed Mozilla Firefox, or simply Firefox, a free and open-source web browser. Firefox displays web pages using the Gecko rendering engine, adhering to current and future web standards. It is a significant player in the market.

Mozilla Firefox was created in 2002 under the code name "Phoenix" by Mozilla community members who wanted more than a single program in their Mozilla Application Suite bundle. Firefox's beta version gained popularity with testers and was praised for its speed, security, and add-ons compared to Microsoft's then-dominant Internet Explorer 6.

In 2004, Mozilla released Firefox, challenging Internet Explorer's dominance. In nine months, Firefox had been downloaded more than 60 million times. Firefox is the successor of Netscape Navigator as it was created by Netscape in 1998 before its acquisition by AOL.

Firefox comes with a few useful features. For example, Firefox has tabbed browsing with individual processes per tab, a built-in pop-up blocker, private browsing, phishing detection, and a sandbox security model. One feature of Firefox that's vital to some users is that it works on multiple platforms.
