I'm very sorry for the trouble you had to go through to restore a working thunderbird.
As I wrote in comment #18, I don't know where that apparmor profile for thunderbird comes from, not from the archive it seems. So I'm reluctant to taking action until I understand better where this comes from, and how many users are potentially affected. But I'll keep an eye on the issue, for sure.
