Mozilla has announced the official release of Firefox 3 beta 2, the tenth major developer milestone in the Firefox 3 development timeline. The new beta, which is available for download from Mozilla’s web site, includes interface improvements and a lot of extra polish.
Mozilla’s quality standards for betas require that all of the planned features be fully implemented and robust enough for daily browsing by a large number of people. That standard was fulfilled last month by the Milestone 9 release, which was the first to bear the beta designation. Additional betas will be released on a consistent basis until all of the implemented features are finalized and performance matches or exceeds that of Firefox. At that point, Mozilla will transition to release candidates to resolve last-minute regressions before the official release. (link)
