Here's a shot that shows how much vertical space can be eaten up with firefox in it's original state, 6 lines. I've got mine down to 3 (I've gotten rid of the bookmark bar since I took the above screen shots).
1 the name of the app
2 the menu toolbar
3 the navigation toolbar
4 google toolbar -- in my case I didn't have this, but I did have the bookmark toolbar
5 the tab toolbar
6 and down at the bottom the status bar
