FWIW, on Nightly you can make your own custom addon list. It's not that they can't support add-ons, but that there are things to work out again before a wide re-release. Fenix, based on GeckoView, is a total redesign. I appreciate it, even if I lose access to one NON-AMO extension that was useful.
Yes, it is possible, but hardly user friendly - each user needs to create an AMO account, create a custom addon list and then copy paste id strings back and forth.
Only then finaly you can actually use an addon from AMO in your Nigtly Firefox.
Frankly sounds much more like jumping through unnecessary hoops than anything. Most users will likely give up than provide much needed feedback to extension authors about how their extensions work on Android.
