Did you ever use sync? Not sure, but maybe copying the data from your previous profile and moving it in the working profile folder may help. I think cor-el can better help with data to movement. https://support.mozilla.org/en-US/kb/profiles-where-firefox-stores-user-data

What OS? What version of Firefox? Did you try Firefox in Troubleshoot Mode? https://support.mozilla.org/en-US/kb/diagnose-firefox-issues-using-troubleshoot-mode#search104
