Hello Carsten,
sorry, I have to add some more guessing ...

Hi Carsten,
as my Thunderbird mail profile (not Thunderbird AA profile) was working
well before the upgrade stretch -> buster and did not work any more
after the upgrade, the upgrade must have got something to do with it.
no, we don't touch or modify any data within the /home folders without
interacting by the user.
The only automatic controlled instance that can make changes to the
users profile is the Thunderbird application itself.
No doubt about that. No data within /home (or wherever my mail profile
is) was touched.
It's just apparmor that behaved different after the upgrade. But as I
don't have a full backup of the system, it's not reproducible.
Maybe apparmor was completely disabled in my installation of stretch and
was enabled during the upgrade? We'll never know. ;-)
BTW: During my upgrade stretch -> buster Thunderbird (and Firefox) was
also updated (from version 60.9.0 to now 68.2.2) and after that I had to
"downgrade" my Thunderbird mail profile. Also a bit weird.
You can't 'downgrade' your mail profile. The only possible and
reasonable action would be to replace the existing profile with an backup.
Well, thunderbird and firefox refused to start after the upgrade. Both
have an command line option "--allow-downgrade Allows downgrading a
profile.".
After starting up with his option, both worked fine with my "old"
profiles. (But also here I have no idea what this option does, just
observing and guessing.)
Regards
Hansjörg
