Not sure how or why but after the last FF update, I lost all of my add-ons. I tried reinstalling them but all of my previous settings were gone including my backup sessions for the Session Manager add-on.

I tried everything I know and still haven't been able to restore them.


Why would FF delete my addons? I just don't get it.

Did you reset Firefox and have created a new profile folder?

If that is the case then you should see an "Old Firefox Data" folder on the desktop with your previous profile folder.

You can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems. See:
