@moktoipas: This is perfect, thanks!

I like the Firefox 3 Tabs Colors. It doesn't look quite right with the native theme for Mac, though.

@Raydancer: That's an awesome tweak, thanks!

Growl notifications is integrated now, no extension needed woohoo!

Well, bummer. I guess I'll try Foxmarks. Now if the Urethane Light theme would be updated for Firefox 3 I'm all set.

I've been looking for something like this. Nice post!
