/usr/share/applications/thunderbird.desktop needs the following change: -Exec=/usr/bin/thunderbird +Exec=/usr/bin/thunderbird %u This enables XDG applications to properly pass URL's (mailto: in this case) to thunderbird so the compose window will be opened when a link is clicked from Freedesktop compliant applications. Made the quick change here, tested, working. Looks / works the same as on all other distributions, matches the configuration of Firefox's .desktop file. Cheers! Reproducible: Always
Ping. Several thunderbird updates have gone by. Any chance we can make this quick change?
