Tonight firefox 2.0 beta 1 release candidate has been uploaded to the mozilla ftp site and can be downloaded from there. Funny thing that happened to me was that I installed the new version and tried to run it but it would only start a new instance of firefox 1.5.0.4. That is until I tried to run firefox 2.0 without a 1.5.0.4 in the background.
