Having trouble moving TB profile to new hard drive. HP Envy 360, Linux Mint 21.3 SSD crashed, but had a backup of the TB profile, not sure of the version of TB because of the crash. (and therefore can’t Export the files) Updated the computer with an M.2 stick and reinstalled Mint. Fine so far Installed TB, (which is 115.18), and have tried to copy and paste the old profile. Got the following message: "A newer version of Thunderbird may have made changes to your profile which are no longer compatible with this older version..." Have tried to import from the saved backup file, and got a red error message. Have tried to replace the Mail file of the new s2p4q…….. default with the Mail file of the backup. Have tried to Can’t figure out why clicking on the 93apdn…… default file only yields “times.json” (see attached pictures) Can’t figure out why in the new profile the 93apdn.. file isn’t the default, and not the s2p4q… I feel the problem may be that I don’t understand why the 93apdn..default has (only) times.json, and that the .ini file lists it as the default. It seemed so easy before, I never had to use Export/Import, it was so much easier to just replace the profile. I know it’s a known issue because others have mentioned it since an update of TB. Any help welcome, thanks
