You have installed apparmor. Have you tried to disable the AppArmor
profile for Thunderbird and check for the further existence of the issue?
$ sudo aa-disable /etc/apparmor.d/usr.bin.thunderbird
This resolved everything.
I had no idea apparmor was installed and active - I had never heard of
it before.
My other computers (all Debian testing, one installed later from the
same install image) have a few apparmor packages installed, but non have
it active - aa-enabled gives "No - disabled at boot".
Thanks a lot for your help.
