Update 2025-07-16: Use either Revanced, NewPipe or Firefox with add-ons. Revanced is my personal pick, due to it being a mod of the official App like Vanced, but better (e.g. it has integration of Sponsor Block, Return YouTube Disklike and more).
I wouldn't recommend Kiwi Browser anymore as it has been discontinued. AFAIK it has been accuired by Microsoft and the extension support has been merged into Edge (Canary). But you'd have to use Edge. Yuck.
