On today’s Firefox 3 status meeting, the need for a second release candidate was confirmed and it has been tentatively targeted for early June.
RC2 will fix about a couple dozen bugs including some top crashers, some affecting performance and localization related. Most of the bugs already have patches waiting for review or landing and the revised code is expected for tomorrow, with initial builds available on Thursday. QA will start the same day and last for about a week.
If all goes as planned, RC 2 should be released close to June 6 for a new round of tests by Firefox users. Depending on whether a new critical bug is found or not, a third RC could be necessary or RC2 will become Firefox 3 final.
