The beta 3 version of Firefox 3, released this week, will probably be the last version of the browser based on the original Mozilla platform, celebrating its tenth anniversary next week. Work is already underway on a revamp of Firefox's underlying platform - Mozilla.
It was on February 23, 1998, that Netscape announced the creation of the Mozilla website as the "focal point for developers interested in modifying and redistributing Netscape client source". It was an historic time for the embryonic open-source movement. Netscape's move happened around the same time that open-source evangelists Bruce Perens and Eric Raymond formalized open-source development with the Open Source Definition.
Although Firefox 3 introduces some changes that will affect many developers given Firefox's growing number of downloads, it should be noted that those promised for Mozilla 2 will also have a far-reaching impact. The Mozilla code has become widely used by a range of hardware manufacturers, from mobile devices to media servers, in addition to regular ISVs, all rolling their own browsers.
