Solution for Firefox 5 Crashes

1.Run Firefox with Add-on disabled: For that, run Firefox, click Help and select ‘Restart with add-on disabled’. Your Firefox should start with all add-on disabled.

  1. Now check Firefox for crashes. If there is no problem, go to the add-on manager (Add-ons – Extensions), disable add-ons one-by-on, and check which add-on is causing problem and disable it permanently. [In my case, it is AVG Safe Search that causes Firefox 5 to crash] Of course, there are several other reasons for crashing a browser like old display adaptor, bugs in browser, etc. You should also look into that, if the problem still persists.
