I figured out why Frederic & I could not reproduce this from a clean Debian Testing install. Thunderbird includes an apparmor profile but it has been disabled by default for many years. See this file: /usr/share/doc/thunderbird/README.apparmor https://salsa.debian.org/mozilla-team/thunderbird/-/blob/debian/sid/debian/README.apparmor It appears like you previously enabled the Thunderbird apparmor profile. Therefore, although this is clearly a regression, I don't consider it to be RC since this is a non-default configuration. Assistance is requested in fixing Thunderbird's apparmor profile. Recent versions of Ubuntu only provide Thunderbird as a Snap, so this issue doesn't currently affect Ubuntu. Thank you, Jeremy Bícha
