VERY useful extension for managing a large number of subscriptions. I ran into an issue a few weeks ago where my Subscriptions list was empty and couldn't see or add new subscriptions to a Group using Firefox. The issue has to do with Firefox's built in Content Blocking. To fix the issue, here's what I did:

Go into Firefox's Privacy & Security section and do the following for Content Blocking settings:

Send websites a “Do Not Track” signal that you don’t want to be tracked: ensure "Only when Firefox is set to block Detected Trackers" is selected.

Third-Party Cookies: ensure "Trackers (recommended)" is selected.

Changing these two settings fixed my issue and now the extension is working great again. As a side note, I am using AdGuard AdBlocker extension to block ads and such in YouTube and this adblocker does not appear to be affecting this extension at all...

Been looking for something like this for a while after having so many subscriptions and this guy did a great job, plenty of functionality and customization. Highly recommend.

This is the answer to an issue I've had for years. Finally.... a non-cluttered experience for those of us with a bunch of diverse subscriptions.

Great addon makes using YT so much better. I have 900+ subscriptions so as you can imagine checking them is really hard but this addon makes it so much easier as you can group channels. Gaming, music, sports, news, tutorials, exploring and asmr is the groups i use.

The only issues I have with it is the way you add channels to the group in the new manager, by drag and drop, It would be nice if you could multi select and then drag them to the desired group as this would be quicker.

Просто чудо!!! Спасибо за такое нужное дополнение! Мастхэв!!!

Good feature to have

everything is simple and functionl

AMAAAAAZING!!!! I'M IN LOVE WITH IT. THIS IS SO GREAT THAT I'M AFRAID THAT THEY WILL SOON START CHARGING FOR SOME "PREMIUM" SH1T.

I love this extension, it does what it says and finally makes having more than 20-ish subscriptions viable by splitting subscriptions into customized categories. Finally for firefox!

upd: Great addon <3
