I've just blocked YT in my browser, and use https://freetubeapp.io/ instead. It's a desktop app, so I don't have to deal with cookies and storage being deleted after every session, just as i can do subscriptions to channels without requiring an account.

So far, it has been an amazing experience, I totally recommend it. And I second the point about Nano AdBlcoker, since I've also been one of the victims, since at the time Nano Defender was one of the alternatives pretty well recommended on Reddit, that was better at avoiding anti-adblock scripts. Plus, any extension you have only makes you easier to fingerprint, thus defeating the point of VPN or privacy focused browser. Especially with Mullvad browser + VPN, which is especially build on the idea of sharing the exact same fingerprint with every other Mullvad VPN user.
