μBlock Origin works for me still (Firefox), but I had to remove my custom filter to remove Shorts from the Subscription page - seems like they can detect it if I have any YT-specific rules.

I've got FreeTube set up as a backup in case μBlock does ever fail - but its lack of tabs really make me not want to use it as my primary access yet. I think they could benefit a lot from creating a browser-based UI, kind of like what Plex has.
