I have been using Thunderbird v91.xxx since it came out and works well. Auto updater was checking, seeing v102, but not doing the update. I apparently made the mistake of telling Thunderbird to make the update using the menu path to force the update. Now I cannot log into my email accounts. I re-tell it the paswords but they are not successfully used and not saved. Note: My profile is stored on a NAS as sometimes I use thunderbird from a different computer on my home network. How do I fix this? OR how do I download version 91 and then revert to that?
