The Firefox 3 developers have been working on a visual refresh that integrates more tightly into the OS, and the Mac OS X version is looking pretty sweet.

Well, if you wanna check out the proposed Mac OS X Firefox 3 UI for yourself, grab yourself a copy of Firefox 3 Beta 1 and go get the Proto theme.
