Mozilla Firefox 1.5 Release Candidate 3, or RC3, is now available for download. This release of the next major Firefox update is aimed at testers, extension/theme authors and Web developers. The final release of Firefox 1.5, which will be widely promoted to end-users, is scheduled for release sometime this month.
This release does not contain any major new features since RC2. There were several fixes to the new automated update system. RC2 users that want to help test software update, should wait for the automatic update to be triggered sometime in the next few days. The incremental update from RC2 to RC3 is just less than half a megabyte.
