What @Vivaldi don't say in their release blog post of version 6.7 today: if you use the updated Vivaldi Feed Reader to watch subscribed youtube channel videos, you don't get to see any ads. Not sure how long this will work until Google shuts shuts this circumvention down, but right now if you're sick and tired of youtube ads, just use Vivaldi's feed reader (it's a great browser/mail program for everything else anyway)
Note that if you do that, you may want to consider other ways to support the folks who produce the videos, (which is generally the case with adblocking. There's no such thing as a free lunch. Make sure that people who create things you enjoy get something in return).
