Would I be notified if an extension update expands its permission scope?

It's possible that I misread the documentation, but I looked for a response to this question for 20 minutes, and I couldn't find a 100% clear answer about my question when it comes to Firefox for Android. Say I install an extension on Firefox for Android, that requires permission just for a specific website (e.g. let's say, for example, it's an add-on for blocking automated translations on youtube, with permission scope restricted to youtube only). Later, the extension automatically updates itself (as apparently, it's not possible to disable automated updates for extensions on Firefox for Android). The update now includes a larger permission scope, for example permissions for some other websites, or even the permission to "Access your data for all websites". My questions are: Is this scenario possible? If so, will I be notified of the changes in permission scope? Would I be able to block the update in this case? Thank you.
