I used to have loads of problems with Firefox, it was so slow... took several minutes to close, it would freeze regularly etc. I got so sick of having to clear the cache every few weeks.
Then one day I noticed their hidden profile manager, created a new profile and used it instead. A few months on and everything is still working like it should. No need to clear caches, it quits within seconds, no crashes and so on.
It's worth a try if you get something similar. Obviously something was screwed up with my profiles, it took a really long time to delete the old profile.
Yep, I used to have a few problems with my addons. Various windows would stop appearing or only partially appear, tree-style-tabs would have funny behaviour. I would assume it was because I was running the latest FF and the add-on hadn't caught up yet...
However, simply creating a new profile solved all my problems. Now, any time I run into an issue, I just create a new profile.
I know some people will simply suggest switching browser, but nothing handles hundreds or thousands of tabs better than firefox, and I'm not looking to change how I browse the web just to go easy on my browser...!
