I downloaded a plug-in (add-on) from Facebook onto my toolbar and it made my entire computer run slowly. I disabled the add-on, removed the toolbar, and everything was still super slow. I went to troubleshooting and hit reset firefox. It was in the process of resetting and my screen went black. I thought it was just the screensaver but after pressing the space bar, screen did not return. I did a hard exit on my Mac and restarted my computer. On my desktop there is now a folder that says "Old Firefox Data". When I try to open firefox I get a message that says "your firefox profile cannot be loaded. It may be missing or inaccessible. I've tried to reinstall firefox as well, only to have the same result. Help!

Do you have JSON backups that Firefox keeps in the bookmarkbackups folder?
If you use the Time Machine then you can try to restore the places.sqlite file.
