AppArmor rule to access https://extensions.gnome.org/
When Firefox is installed via PPA with activated apparmor (sudo apt install apparmor-profiles apparmor-utils
then aa-enforce usr.bin.firefox
, details and tweaks here), then Gnome extensions can't be managed through Firefox any more, because apparmor is blocking access.
Does anybody here know a proper apparmor rule?
The solution could be added to the wiki, like KeePassXC did.
As a prerequisite, you have to sudo apt install gnome-browser-connector
and install https://addons.mozilla.org/firefox/addon/gnome-shell-integration/.
