Go here to get the Mozilla 1.2 release.

Also, Phoenix 0.5 is going to be released using Moz 1.2 source code and will be out next week. The name is being changed to some other name for legal reasons. New name has not yet been announced.

Update: You might want to wait a day and get the Mozilla 1.2.1 rev that fixes a few last minute regression problems. Though I'm using 1.2 without any problems myself.

UPDATE: Mozilla 1.2.1 is now released. Get 1.2.1 rather than 1.2.
