Nord. Doesn't do crap for YouTube (the app anyway, and there are advantages to using the app, signed in no less...god I hate YouTube) as far as I can tell.
This new one has upgrades available for payment, and mentions better ad blocking for YouTube, but species in browser... something tells me doing it to the app isn't easy. It does seem I have less middle ads, but still get one banner to start.
Anyway, will research further
