Upon updating to Thunderbird 78.10.12, my Thunderbird system became corrupted and unusable. All previous preferences, toolbars, and mail folders have been lost or distorted , and I can't seem to be able to correct through Account Settings or preference settings. Archive, Receipt folders gone. Trash contents gone.
