on ios you can also use firefox focus, it doesn’t have ads on youtube, but iirc you can’t stay logged in because it doesn’t save cookies (tho that could be a positive depending on how you look at it)

vivaldi ios also didn’t have ads on youtube, but it’s been a while since i used it so it may have changed and it’s a pretty heavy browser in my experience

orion also supports firefox/chrome extensions but in my experience it’s adblocking (even with ublock) isn’t perfect. but again, it’s been a while so maybe it’s better now
