I am having Problem with this release it's keep getting crashed whenever i open more than 15 tabs and some time opening some randomly selected tab, it just crashes, i have uninstalled it and reinstall it with new downloaded file but the problem is still there.
If it is not happening to you please tell me how to solve this problem.?
I've run 3.5.3 with far more than 15 tabs and encountered no problems.
The most common suspect is one of your add-ons. If you have a lot of add-ons, then try starting Firefox from the Windows Start Menu and select the "Mozilla Firefox (Safe Mode)" option. If you have no further crashing problems after doing so, then re-start Firefox in "normal" mode, and go through and manually disable all of your add-ons. Then re-enable them one by one, testing at each step, and see which one is causing the problem.
You could also have a more general problem with your computer, or you may have found a real-but-uncommon bug. The add-ons are the most common cause of problems, though.
