I have to say, I also am very fond of this Proto look -- big 'back button' and all. Everything is clear and easy to find right away. If I wanted a clone of Safari, I can easily get one here called 'GrApple Yummy (blue)'. Without a doubt, it does look very much like the latest version of Safari. BUT. This was the first time I felt I could use Firefox right out of the box without hunting for something that made it 'look decent' on the Mac. And that is really a giant bonus for me, as this beta works SO WELL for me that I doubt I'll ever go back to Safari again (on this computer -- I run about half a dozen different ones). The tip provided here by 'gl0tzk0wski' perfectly addresses those who do NOT like the large back button. Simple solution -- love it!
Firefox DOES need a 'look' unique to itself for branding purposes, and it is my opinion that they have found it and darn near perfected it on the Mac. I, like 'Jules' here, also use the graphite colouraton, and would really like a way for this to automatically integrate with my system. I'm sure this will happen as time progresses. I suppose my only beef would be that little 'black' Home icon. Something should be done to clean up that 'blotch'. Maybe have a look at the GrApple way of dealing with it? In GrApple, it is visible, but tastefully treated. I would also like to see the search engine icons either 1.) dumped completely with just the words identifying which one is use or 2.) the icons rendered as black line only. Currently, they look too garish and arcade-like for my taste. The GrApple theme does it right.
Other than that, I think the development team working on this Proto theme is doing a super job on the Mac side. Now -- since I work on the PC (WinXP) too, how about some clean-up for that version? It really just looks gawd-awful messy with all those icons in the Bookmarks Toolbar.
Overall I give the development team extremely high marks for a unique, yet super looking Mac theme, to compliment an outstanding browser (even still in beta!) that is destined to become my standard on ALL platforms I use.
Thanx for all your hard efforts to date, as I truly appreciate them!
