HistoryeditThe Firefox project began as an experimental branch of the Mozilla project by Dave Hyatt, Joe Hewitt, and Blake Ross. They believed the commercial requirements of Netscapes sponsorship and developer driven feature creep compromised the utility of the Mozilla browser. To combat what they saw as the Mozilla Suites software bloat, they created a stand alone browser, with which they intended to replace the Mozilla Suite. On April 3, 2. 00. Mozilla Organization announced that they planned to change their focus from the Mozilla Suite to Firefox and Thunderbird. The community driven Sea. Monkey was formed and eventually replaced the Mozilla Application Suite in 2. The Firefox project has undergone several name changes. It was originally titled Phoenix, which carried the implication of the mythical firebird that rose triumphantly from the ashes of its dead predecessor, in this case from the ashes of Netscape Navigator after it had been killed off by Microsoft Internet Explorer in the First browser war. Phoenix was renamed due to trademark issues with Phoenix Technologies the replacement name, Firebird, provoked an intense response from the Firebird database software project. In response, the Mozilla Foundation stated that the browser would always bear the name Mozilla Firebird to avoid confusion. After further pressure, on February 9, 2. Mozilla Firebird became Mozilla Firefox. The name Firefox was said to be derived from a nickname of the red panda,4. For the abbreviation of Firefox, Mozilla prefers Fx or fx, though it is often abbreviated as FF. The Firefox project went through many versions before the version 1. November 9, 2. 00.

Script APIs and is designed to be similar to the Google Chrome4. Microsoft Edge extension systems, and run within a multi process environment, but does not enable the same level of access to the browser.
