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 :)

Works great but it's stuck on light mode in Firefox

It would be great if this thing did not freaking restrict the freaking search bar. Stop putting stuff into a paywall

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
