I just finished building optimized Firefox builds and have now posted them for download. There are now optimized builds for every Mac CPU currently available (G4, G5, and Intel Mac) and Firefoxy and native aqua form widgets available for the G4 and Intel builds. The G5 build is aqua form widgets only (and no, there won’t be a Firefoxy build for the G5 so don’t ask).

Here’s what’s new according to the Mozilla changelog for Firefox 1.5.0.4:

* Improvements to product stability
* Security fixes (more details on this here)
