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.

I find this extension to be an excellent replacement to YouTube's Collections feature that YouTube removed, and it works more or less as it should with only mild difficulties from time to time. When there are difficulties that are typically caused by user inexperience, but even this is addressed with tutorial videos.

I do, however, wish that there was a mousehover/hoverbox when my mouse is hovering over a subscription group, because the YouTube sidebar/menu-bar is so short, many of my subscription groups have their names cut-off, and without a way to widen the YouTube sidebar/menu-bar, the only way to see the full name of my groups (some of which may have similar names) is with a mousehover.

Otherwise fantastic work, my compliments to the developer

I tried to use this add-on for mozilla fire fox, but the subscription list does not appear, therefore I can not add any to a specific group.

I love the fact that I can now organize my subscriptions in YouTube.

Hi,
Very nice extension, however I have a problem. Somehow I created a folder which cannot be removed or renamed. Is here any chance your program stores data localy so I could delete it manualy ?
It makes me crazy :/

Thank you

Love the add in but all of a sudden I can't add new sites to subscription groups in Firefox. I am able to add the groups in Chrome though. Any ideas?

Update 7/8/18:
On 6/13 I sent the developer a couple of screenshots because he requested them in a private email he sent me on 6/11. I am assuming that he received the email. I have not heard anything further from the developer regarding the issue I presented. I am still hopeful that there is a resolution to my problem. I have removed another star from my review, I will be glad to give 5 stars once the issue I am experiencing is resolved.

Update 7/25/18:
Since I still haven't received a response from the developer I uninstalled the add=on and then reinstalled it. This did not correct the original issue. I noticed that even though I uninstalled the add-on the subscription groups I created were still present after I reinstalled it. I wonder if there may be a limitation to how many subscription groups or subscriptions you can have in Firefox. As I originally stated I do not have this issue in Chrome.

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.
