Also worth noting it's automatically disabled if telemetry ("Send technical and interaction data to Mozilla") is disabled.
Though even without disabling it, PPA is currently in limited rollout and only visible to Mozilla websites in the first place, so it would hardly cause any harm for now.

When I was using FF, i noticed that updates often revert settings to default. What pissed me even more was that there is no clear "Disable auto updates" checkbox, I had to create policies.json file in Contents/Resources/distribution folder for that. This was hostile, I'd never win the battle with developers.
