Mozilla: Final Version of Firefox 3 Will Ship in June
The final release of Firefox 3 is due in June, the company said Wednesday during a roundtable discussion with a small group of tech bloggers.
Right now, the latest Firefox 3 release is beta version 4. The Firefox 3 betas have about 700,000 users right now — a small but dedicated chunk of Firefox’s entire user base of 160 million people. The public release of Beta 5 will be out the first week of April (the nightly builds are available for testing now), and that will be the last beta release before Firefox enters the release candidate stage. - Wired
Supposedly Firefox 3 will have improved memory use and faster performance then IE, Opera and Safari.
