Somehow I managed to lose all of my windows, search history, addins, etc. It would appear that a new profile was created. I tried about:profiles and selecting the old profile (1.4GB) but while FIrefox starts, the places.sqlite file is now place.sqlite.corrupt. I followed the Mozilla instructions to try to fix the sqlite file but that did not help. I restored the full Firefox Application Support folder from Time Machine but that also starts with a fresh profile and selecting the old one gets me to a corrupt places.sqlite file. Given that I have TIme Machine backups, Is there no way to get back to a previous state with my windows, history, addins, etc. I am faced with losing a lot of work if I can't get back to where I was at least since a recent backup.

Thanks in advance for any assistance you can offer.
