Ich starte hier™ den FF als transient Unit:

systemd-run --user --unit=firefox-user /usr/bin/firefox

Das sieht dann so aus:

$ systemctl --user status firefox-user.service --no-pager
● firefox-user.service - /usr/bin/firefox
     Loaded: loaded (/run/user/1000/systemd/transient/firefox-user.service; transient)
  Transient: yes
     Active: active (running) since Mon 2022-10-31 17:56:15 CET; 15min ago

Eventuell kann man das ja mit dem genannten systemd-oomd verheiraten.
