Firefox 91.7.1 / iMac
GREAT extension, I have a ton of subscriptions and this add-on allows me to quickly see new uploads organized into groups of my own creation...without have to scroll through dozens of channels individually. Bonus: the channel display of groups in YouTube Subscription manager defaults to their "uploads/video" list. Otherwise I often have to click that link on a subscribed to channel to bypass their intro videos/shorts/playlists or w/e. Good stuff!
The only "glitch" that doesn't even bother me is often having to re-load the Youtube main page to get YTSM to display new video counts next to my groups...like it needs to read the home page after it loads up or something...otherwise it's 100 percent.

В настоящий момент функционал расширения отключен самим автором
У него война в стране и таким образом он пытается обратить внимание людей
Я честно ему сочуствую, что творится на Украине это настоящий кошмар!
НО! К дополнению я ОЧЕНЬ сильно привык, заменить его реально нечем (
Без него я вообще как без рук в каше подписок
Так что народ, кто также сильно нуждается в данном дополнении
1. В настройках браузера запрещаем обновление данного расширения
2. Качаем старую версию (XPI файл) и перетаскиваем его на браузер (предложит установить)

Иной способ установки
- закрыть браузер
- перетащить в папку расширений в браузере - Mozilla PATH\profile\extensions
- открыть браузер

Само расширение оригинальное, ничего туда не добавлено и т.д
Все подписи в манифесте или где они там прописываются все теже самые
Да и мозилка вроде не дает не подписанные версии ставить

Автору могу только сказать "держись"
Я тоже желаю, чтобы этот дурдом как можно скорее закончился (
Извини, что выложил старую версию твоего расширения

Good add-on... It was... But stopped working after the latest update (on March 1?)
Firefox 91.6.0esr
Can you please return everything back when it was working normally?

This extension has single handedly made my YouTube experience out of this world. Thanks app i can actually decide what i want to watch and only watch that.
The supporter expansion has made my YouTube better than cable TV. I can choose which Category of Videos i want to watch and be shown only that.
I have been using this app since 2020 and Never had any complaints.
**One wish i have is to be able to add the group sync and backup for Firefox like how it is on chrome. however i can sync groups with Firefox sync to other PCs.

This takes care of my pet peeve. I love your work, human being responsible for this. I love your work.

PERFECT. It is an amazing app with useful features. 10/10

Love this. Thank you.
A small wish? After I've viewed a vid, it can be filter out in the Subscriptions feed, that is good. Can also that vid "loose" its blue dot on the channel under Subscription Groups and my custom groups? Because now I view random vids in my subscription feed, and if I have time I dive deeper into my Groups to update my self on the channels to catch up on vids I missed in the feed. But very often I find that I've seen the latest vids on channels, but the channels are still "tagged".

And the Deck function on Firefox are only loading (spinning) when I open the deck. In Chrome it works correctly. Thank you.
Edit: Last version 11.0.4 has corrected this! Thank you!! 5/5 stars :)

My wish-list:
1. Store custom group images locally, not on Imgur
2. Delete Imgur image after sub group deleted
3. I have no clue where you store the group playlist(50 videos). The playlist is "Unlisted" and the owner is not me. You can create 100+ videos playlist on my account and set it to private, why not do the same thing when creating 50 videos playlist?

This add-on is 5/5 useful and easy to use.
But...
Privacy 1/5

Edit to 5 star because dev answered my question.
