Head on over to Mozilla.com to grab the latest release of the almost-finished Firefox 3 if you’ve been keeping up with the various betas and release candidates. The second release candidate should probably be the last one before the browser makes the leap to the final version and word on the street is that this latest iteration is definitely stable enough to use full-time.
Firefox 3 Release Candidate 2 appears to be mostly bug fixes and behind-the-scenes updates. If you’re running and earlier version of Firefox 3, you should be able to update the browser through the Help menu. If not, you can download it directly here.
