...

Changing /usr/share/applications/thunderbird.desktop to .../thunderbird-esr.desktop solves the issue.

With wayland, the application tells the DE what its .desktop file is. You can check that with

WAYLAND_DEBUG=1 thunderbird |& grep app_id

If it shows thunderbird-esr, TB code needs to be adapted.

Thank you.
