FireFox


Hi:

In addition to the great advice already offered....

...Most problems with Firefox originate in the user's profile, not in the program itself.

A specific suggestion for the issue you report:

Firefox - Profile in Use

Then, there is a logical sequence for Firefox diagnostics, which (as already suggested) generally starts with Mozilla Safe Mode (not to be confused with Windows Safe Mode):

Firefox - Standard Diagnostic
or
Fix slowness, crashing, error messages and other problems

Resetting Firefox (as already suggested) is certainly a reasonable option, but there are other, less "destructive" steps one might consider first.
There are also more drastic steps, such as creating a new profile. This is sometimes the best way to get back up and running, if the existing profile is highly corrupted.

Please let us know if you need more help.

Thanks,
MM
