That's for the extension devs to handle. I'm personally in favor of the following: 1) Users can enable or disable any permission they like 2) This is transparent to developers - i.e. if you access geolocation, you'll always get one. It just won't be the right one if you don't have permission. 3) The extension is allowed to query which permissions I've given. So devs can handle blocked permissions more gracefully if they choose.
