Firefox 3 Beta 1 is out and there are a few nice new features. I took a few minutes and played around with it and here are my findings.
The Install DMG still doesn’t include an alias to the Mac Applications folder. Come on Mozilla, get this one working please.
Once installed, the new Mac theme doesn’t take effect. You actually have to go download it. But once installed, it looks very nice. (Not sure about the Windows one.)

Bookmarks are integrated better. Simply star a page and it’s added, click the star again to rename it, add tags, put it in a folder or delete it.
