Why is my Mozilla Firefox ALWAYS freezing two of my computers?
In my two computers, the memory starts at about 70,000 K. A Half an hour later, I always find because Fin Tasking Firefox memory on average is around 1 million K!?!? I do not do anything hardcore on it. Just e-mail, facebook research at school, and Yahoo Answers. I use Firefox version 3.0.15 if that helps. Thanks and God bless! Is it possible I can solve this problem? If it helps even more, both computers are XP and Vista (64-bit)
Try opening it without add-ons Safe. See if you still is a memory leak. I guess one of the add-on has a bad code and memory leaks. If it works Well, then try removing the add- Firefox one by one and test your browser. You can easily find any add-in that is the cause. Also Firefox version 3.5.4 is now I think. Why do not try to upgrade your browser. Also check for updates to your accessories.
