Mozilla is celebrating the fifth anniversary of Firefox 1.0, released November 9, 2004. The project began as a fresh start intended to be leaner and faster.
While the official Mozilla effort still was working on the unified browser and e-mail software package dating back to the Netscape era, Dave Hyatt and Blake Ross began work on a simplified browser initially called Phoenix. This is the logo for Phoenix 0.1, the first milestone of the browser. It was released in September 2002, but the name triggered a trademark infringment challenge from Phoenix Technologies.
