Public bug reported: After running firefox for a few minutes it starts to get very very slow.
After several hours it becomes essentially frozen. Checking top I see Firefox and Compiz both high usage. Firefox ~ 100% and Compix ~24% (dual CPU 200% total) Using Unity2D I do not have the problem. I have only noticed this problem on Firefox. All other apps seem to be working OK. I have reported this using ubuntu-bug that collected a lot of information so I assume you have all the relevant version info. If not I can supply it.
