i am a subscriber as firefox + ublock origin does not work on phone (on android, i think? last time i checked) and neither on smart tvs (mine is rokutv)
NewPipe and IronFox (hardened Firefox) for Android, although I suspect these need to be "sideloaded" as Google won't allow them on the Play Store. (I run Graphene so this does not apply to me.)
For the TV, I would suggest VacuumTube (a frontend to the Leanback interface) on a free/libre box running Linux.
