Continuing pressure from the Firebird community forced another change, was chosen for its similarity to "Firebird", but also for its uniqueness in the computing industry.To ensure that no further name changes would be necessary, the Mozilla Foundation began the process of registering Firefox as a trademark with the United States Patent and Trademark Office in December 2003.
The Phoenix name was kept until April 14, 2003, when it was changed because of a trademark dispute with the BIOS manufacturer, Phoenix Technologies (which produces a BIOS-based browser called Phoenix First Ware Connect).
The new name, Firebird, met with mixed reactions, particularly as the Firebird database server already carried the name.
In response, the Mozilla Foundation stated that the browser should always bear the name Mozilla Firebird to avoid confusion with the database software.
The project that became Firefox started as an experimental branch of the Mozilla Suite called m/b (or mozilla/browser).
After it had been sufficiently developed, binaries for public testing appeared in September 2002 under the name Phoenix.
This name 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's Internet Explorer in the "First browser war".The history of the name Mozilla goes all the way back to the internal codename for the original 1994 Netscape Navigator browser, with the name meaning "Mosaic killer" and aiming to some similarity with the building-crushing Godzilla, as the company's goal was to displace NCSA Mosaic as the world's number one web browser.The Mozilla Firefox project was created by Dave Hyatt and Blake Ross as an experimental branch of the Mozilla browser.Firefox 1.0 was released on November 9, 2004, Firefox 1.5 was released on November 29, 2005, and version 2.0 was released on October 24, 2006.Firefox 3.0 was released on June 17, 2008, with version 3.5 and version 3.6 released on June 30, 2009 and January 21, 2010, respectively. Since the version 5.0, a rapid release cycle was put into effect, resulting in a new major version release every six weeks on Tuesday.The latest version, Firefox 48.0, was released on August 2, 2016.
