I have been having issues with firefox for a couple of weeks. Things like it not minimising, or not closing. Or not being able to type into the URL bar. I got so annoyed i've moved over to Camino in hope of better things.
Well which ever version i had, it was playing up every single time i used it, so i dropped it.
I just checked and i am running 2.0.0.2 ... so im guessing the update hasn't solved any of my issues as i have been having them for about 2 weeks at least.
