Firefox 2.0 Beta 1 Candidate Now Available

The second set of release candidates for Firefox 2.0 Beta 1 have been posted to the Mozilla FTP. You can get this build for Linux, Mac, or Windows (Installer or ZIP). The final release of Firefox 2.0 Beta 1 has also been pushed back to later this week.

A newer build can be found here.
A portable version of this build is also available.
Also, I have put together a nice guide on tweaking Beta 1 and some of its new features.
