I’ve received this notification about upgrade to Fenix and the article mentions that my addons will be migrated as well 
However it seems that they will also get disabled, unless they’re one of those lucky 9 
So if my Firefox for Android upgrades in upcoming weeks and I will loose access to my addons, I will be very unhappy (to put it mildly). Especially when I know my addon is compatible and could work.
Is there some solution to this problem?
I don’t mind staying on old Firefox as long as it receives security updates.
Also I don’t mind flipping some “about:config” pref that would enable disabled addons.
