Thanks, using "usr.bin.thunderbird" did it. Before, I also did sudo systemctl stop apparmor.service sudo update-rc.d -f apparmor remove sudo systemctl start apparmor.service sudo update-rc.d apparmor defaults but I am not sure, if this is related. Should this be included in the installation process somehow? This may effect other users as well, since I do not think my configuration is very special. However, I do not understand the technical details here. This is the second time, that an automatic update in Ubuntu destroyed my working environment (after the update to 60 that broke all addons, including calendar).
