I completely uninstalled Firefox . Only this time when the Firefox uninstall dialog box popped up I checked the option "Remove my Firefox personal data and customizations". I then completely shut down and restarted. Then reinstalled Firefox, and thereby creating an entirely new profile from scratch.

User profile . I hovered over the first file /shift /to the last file . Right click /copy , up one folder to the parent folder which held both profiles . Hovered over the new profile and clicked paste . Prompts said <em>replace existing files </em>I clicked yes to all until it stopped at a corrupted file and prompted me that that file was corrupted . I went back and blocked everything from the first to the file before the corrupted one pasted them in the new profile . I repeated this process until all of the corrupted files were bypassed and all of the usable files were transferred to my new profile .
