Actually, what you did is very unusual. Crossgrading from Ubuntu to
Debian is not supported. Ubuntu's thunderbird packaging was managed
completely separately from Debian's and I believe it didn't provide an
apparmor profile. Your situation may not have been handled by Debian's
postinst script.
If it is a symptom of my unusual upgrade path, this is the first major
one. It's been long enough that I almost forgot that this started as an
Ubuntu install many years ago--long enough that any backups of the
original Ubuntu install I may have made are long gone so I can't go back
and check to see what was there.
If that apparmor profile didn't come from the Ubuntu package, then I
don't see how that's a cause of this specific issue.

I recommend that you make time to do a clean Debian install. Most
packages on your system are probably ok, but there may be a few like
thunderbird where you accidentally have a non-default install which
can lead to unexpected behavior. The problem is that it's not easily
possible to tell which packages are in this unintended state. Backup
your user config and data before doing a new install.
I am noting this advice. However, to be honest, this computer is
probably nearing end-of-life (it originally came with Windows 7, it's on
its second power supply, and that form factor power supply is becoming
increasingly rare, in addition to the usual obsolescence). I expect to
either retire it by the end of 2027 or install some other OS on it
before that date.
