App Armor for Firefox

Not exactly an app, but one button to enable App Armor for Firefox would be cool.

Right now these commands are required:
sudo apt-get install apparmor-utils
sudo aa-enforce /etc/apparmor.d/usr.bin.firefox


More generally, coming from macOSX (where perfectly clear apps like Little Snitch are available for years), do I understand correctly there is just no GUI for AppArmor on Mate?
Or any alternative (like the ‘Douane’ project I saw, which installation seems to require a number of pages on its own)?
