Since the transition to GeckoView the tablet ui is just scaled up mobile ui, with no tab-bar and no desktop sites by default. For some reason mozilla has marked it as a feature request instead of a bug (which I argue it is, as it used to have those features, as do all of the competing browsers), and successfully have been ignoring for 3 years (here’s the discussion on mozilla connect, but there used to be a github issue before that).
As for youtube, I need a browser to use https://chatreplay.stream/ . For everything else of course there are NewPipe, ReVanced, and LibreTube
