I just migrated from 21.04 to 21.10, and as a result, I'm now defaulting to Firefox snap package.
It seems this breaks Browerpass plugin, with this error:
Error: Error: Attempt to postMessage on disconnected port
It also seems to break Gnome extensions management from Firefox.
So, what are the possibilities/limits of Firefox snap package regarding plugins, especially those that rely on Native Messaging ?
