I have migrated my profile for Thunderbird (TB) from an old machine to a new machine, both running Ubuntu 20.04.4LTS. Both have TB 91.7.0 installed via apt. The Profile folders are located on a separate NTFS partition. I opened a terminal and ran "thunderbird -p" to open the profile manager. I created a new profile and pointed it to the profile folder path (path/to/ntfs/partition/Thunderbird/Profiles/xxxxxxxxx.default). I open TB but only see the "welcome page" asking me to setup a new account. When I check the profile folder under about:profiles it shows me the correct path. What could be the issue? I appreciate your help! For migrating Firefox everything worked smoothly using the same procedure.
