Do you have any AddOn installed that might cause this? Please disable all AddOns and see if the issue is still existing. > Kernel: Linux 5.10.0-trunk-amd64 (SMP w/4 CPU threads) > Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), > LANGUAGE=en_US:en > Shell: /bin/sh linked to /usr/bin/dash > Init: systemd (via /run/systemd/system) > LSM: AppArmor: enabled I see you have Apparmor enabled. We had cases were Apparmor did make some trouble. Please check also if disabling Apparmor has some effect. The reportbug template does not show if the Apparmor profile for Thunderbird was active, so please have here a look too. If the issue is still happen it's very likely it's an upstream issue and needs get reported on https://bugzilla.mozilla.org/home Could you mind filling (or searching for a similar) issue there and point to the bug report then? -- Regards Carsten
