I maintain a list of working addons.
All of them work on mobile, most of them perfectly without issues.
At the moment mobile seems even more limited than it actually is. Yes looots of features dont work. It is even more restricted than FF desktop. But there are actually tons of working addons!
Please make Firefox mobile more user friendly. Its not actually that restricted.
Firefox mobile has addon support. This is unique. Make it shine by not restrict it like that, you are killing that browser otherwise.
