It works even when I'm not logged-in in YouTube! So it's perfect if my browser deletes cookies after every restart. It would be even better if I could mark specific videos as Watch Later :)

Excellent functionality.
Just what I was looking for. I have literally 1000's of subs which was impossible to manage. Thank you my dude.

A bit slow
Update: Hi, you were right. I was investigating in a private tab. An extension called "600% Sound Volume" was really messing with my Youtube subscriptions page with this extension on. While looking through their extension reviews, I also found that their extension apparently injects code or something. Anyways, yeah, I removed the extension, and everything is fine now. I increased the rating to 5 stars, as it does everything I need it to. Thanks

only if it was available on android :(

Seеms that pockettube banned all users with russian language in operating system. developers need to now, that russian language is internetional language for many countries, like Kazakhstan, Armenia, Azerbaijan, Tajikistan, Turkmenia, Kyrgyzstan, even for Georfia, and Ukraine. So banning russian language, you banned a lot of users, that never was related to Russia-Ukraine relationship. If someone says that war in the Ukraine more important than anything, i will say when war was in my country, world went on, and no one did not condemn the agression against my people. Ukraine not special.
Upd. Last usable version for me is 11.0.11. Any above version just dont work. Im not from Russia or Ukraine. And understand your position. But something looks broken.
Upd 2. Thanks, changing country from Russia helps. Unfortunately youtube has no Armenia in country choice, so i was using Russia.

I like the recent update. Though there is a bug at the Subscriptions page that appeared after that. If, say, I filtered out one group before I finished my previous session of browser. In the current session, I made some changes to the filtering (e.g., include that group back in). The changes would be applied normally at first glance, but when I scroll down the subscription videos list far enough such that the loading icon appears, after the loading finish the filtered results would be reverted back to the previous state (i.e., before I made the changes), and I have to change the filters again for it to work normally again. This would happen once for every session of the browser (i.e., if I restart Firefox this would occur again). I think this has something to do with how the filtering option is cache.
