Firefox crashes non-stop!!!

I have went back to Firefox 3.6 for this reason.

With the newer Firefox releases, I would find that it would crash and cause my whole system to hang and the only way I could recover from it would be to boot Windows 7 in safe mode, uninstall and then reinstall Firefox.....but bollox to that every 1-2 days.

 

Add-Ons for Firefox crash since update to 80

I left Firefox open over night and attempted to login to LastPass this morning - all the addons crashed. I had Firefox Task Manager open at the time and before attempting the login all addons were in the list and not using very much resources. After attempting login, all of the addons disappeared from the Firefox Task Manager list.

I will try the additional suggestions.

If I want to try a new profile without losing my saved/sync profile (and hopefully with the option of syncing my data back into the new profile) what steps should I take? Or is it just a given that if it is profile corruption, the sync profile is junk...?

Thanks!

 

Firefox crashes non-stop!!!

Suggest any methods to stop Firefox from crashing. It crashes right after starting, no more than a second or 3..

Any cache, plugins, antivirus things that might cause it? It is very, very annoying...
