ADDITIONAL INFORMATION
Comment 1 Arjen Hiemstra 2021-08-02 13:21:31 UTC 
There are two possibilities here: Either Thunderbird is not launching Firefox in its own CGroup which means plasma-systemmonitor cannot know it is a separate application, or alternatively, it is creating a CGroup with the wrong name and thus we match it to Thunderbird instead of Firefox.

Please share the output of systemd-cgls to confirm which one it is.

Comment 3 Nate Graham 2021-08-03 19:45:24 UTC 
Looks like the former. This would then be a Thunderbird bug, right?
Comment 4 David Edmundson 2021-08-05 13:56:23 UTC 
Yes, though lets investigate a bit more to see what it's actually running.
Comment 5 David Edmundson 2021-08-05 15:57:30 UTC 
Thunderbird is launching through g_app_info_launch_default_for_uri.

Will prepare a report there and then close this.
Comment 6 David Edmundson 2021-08-05 16:17:32 UTC 
Apparently a patch exists, Fedora has been shipping it since F34

It isn't merged upstream in GIO
