It's really cool that Mozilla 1.0 is finally out, I just wish it were more stable than 0.9.9RC3...
The previous one occasionally had trouble with the address bar, in that it'd get stuck on the address of one of the tabs, and never change when switching or even for new tabs. Now that bug is still there (even though I'm sure I saw it on bugzilla) but instead of it being just the address bar it's the entire top section. That means that if what it gets stuck on didn't have a back or forward history, you don't get it either. And that sure does suck...
another few days and I'll revert to the previous to 0.9.9...
