Migrating profile to new Mac: Cannot get Thunderbird to recognize old profile
I have a profile that started on a PC and moved to Mac (Sonoma). I now want to put on another Mac from a backup. I have tried linking to the old profile using Profile Information. I click Create A New Profile and highlight the old profile after moving it into the User>Library Profile Folder, but I only get a new profile and not a link to the saved profile. What am I not doing or not doing right.
Also, in the past, there were two items in the Library>Thunderbird folder showing links to the profiles automatically installed when the program was installed. These had to be removed when installing my own existing profile. Those install links are not present. I'm attaching a screenshot of the T-bird folder.
Thank you.
