Same, I use Firefox + uBlock Origin + YouTube Unhook for a cleaner interface. I also always watch videos on private navigation windows (my default way of browsing the internet) and I manage subscriptions with the RSS feed of the channels, much better to track what I have watched since the default homepage of YouTube does not display the last videos of your subscriptions.

Edit: I have forgotten to add sponsorblock to the list of extensions

One of the benefits of ublock origin for me is blocking the youtube comments section, along with all of the video overlay elements.

I'm using Firefox + uBlock Origin logged in and it works totally fine. Maybe Youtube removed the anti-adblocker on select accounts? I remember I once entertained myself with writing a report in which I sounded like I'm sitting in a retirement home and have no clue what's going on with "ad block." Did perhaps someone actually read this?
