After various old (example) and new (I'll spare you) hassles with the Thunderbird Snap, I want to try migrating my 8GB of saved emails and config settings to a Mozilla release channel that will auto-update via the Mate Software Updater app or some other automatic method. I've read many posts about why Snap is good or bad, and hope we won't have to re-litigate all that here. I just want to migrate and see if it works better for me. If it doesn't, hopefully it will be easy to go back to the Snap.
It looks like Snap mail & config stuff is all in:
/home/me/snap/thunderbird
I've backed that up on another partition, but is there anything else to do before uninstalling the Thunderbird Snap?
What's the current recommendation for then installing a non-Snap current Mozilla version of Thunderbird that will auto-update via the Software Updater app or the best alternative method? Will getting updates require manually doing something like apt-get update
instead of some "push" automatic method?
Once I get non-Snap Tbird working, will it be obvious how to port the config and mail files over? As I recall, the Mozilla version used an alphanumeric Profile subdirectory in this directory:
/home/me/.mozilla/thunderbird
So presumably I could just launch and exit the new Tbird installation, then move everything into the directory structure it created?
