Firefox 2.0b2 RC1 is already available in the FTP for windows, linux and mac. This will be the first release candidates to try detecting any bugs or stability issues, there will be certainly another RC2 after it before the official release of Firefox 2.0. The first RC1 have been delayed many times due to several issues, and according to Mozilla Dev News it’s now scheduled midday on August 23rd. Anyway what you’ll find on the ftp is a nightly build so use it at your own risk.
