I have had TB installed before today with a myriad of settings, extensions, mailboxes and whatnot. This morning, I accidentally upgraded TB using winget (the hyped up MS package manager). The new installation opened as though I had never used TB before, asking me to connect an email address. Also, all the configurations, settings, extensions have gone. I have looked in the profiles directory under C:\Users\thymaro\AppData\Roaming\Thunderbird\Profiles and my profile from before seems to reside still in this location. After backing up the profiles.ini file under C:\Users\thymaro\AppData\Roaming\Thunderbird, I deleted a few lines that were written by the new installation, so that my old profile would be loaded instead of a new one being created. I also deleted the new profile diretory to motivate TB to use the original profile. '''That didn't work'''. '''I guess some settings were changed elsewhere that tell TB to create a new profile and to forget the old profile, but what do I need to edit to make TB fall in love with the old profile once again?'''
