I know how this extension is supposed to work because it works just great in Chrome, but I simply can't make it work in Firefox. My Youtube subscriptions remain resolutely ungrouped. My support request to the developer unfortuately bore no fruit.

Грузит процессор на 30 %, после отключения все норм.

used to work but now it doesn't even show up on my you tube i installed a older version specifically 8.014 that version seems to work but none of the newer ones work
it has three Warnings listed

Reading manifest: Warning processing options_page: An unexpected property was found in the WebExtension manifest.
Warning details

Reading manifest: Warning processing oauth2: An unexpected property was found in the WebExtension manifest.

Reading manifest: Warning processing key: An unexpected property was found in the WebExtension manifest.

the console also shows this error
Uncaught (in promise) Error: Could not establish connection. Receiving end does not exist.

extension no longer works

Are the subscriptions groups stored locally or synced with my firefox account?

Great Addon !

It would be nice to add a video search option only among a single group, because the subscription search doesn't allow to search ALL videos, like a channel search.

This add-on is God sent! Now I watch what I want when I want. I want to make 1 small suggestions (will definitely buy developer a few coffees if these are added):
* Allow videos within a group to be sorted by view count (this to me is the best way to catch up on the best videos that I never got to see from some subscriptions). As of now they can only be sorted by upload date

Regardless of these improvements, this is a great add-on that definitely deserves 5 stars

Вот хочется иногда "Поддержать разработчика", но устанавливаешь дополнение, а через неделю оно уже не работает...смысл поддерживать, если меня никто не поддерживает? Я не знаю чей - это косяк, разработчика или мазиловцев, поэтому ставлю тройку...дополнение-то полезное, удобное...

An excellent add-on overall that replaces — and exceeds! — a basic feature removed from YouTube years ago.

Ultra happy with this extension; I'm finally able to use YouTube to get the content I want, not just click-bait. Just bought Dmitry a coffee after he fixed a issue because of a change from Youtube (in only two days); definitely recommend all fans do the same to keep this going!

Хорошее, нужное расширение.
Не забрасывайте его. )

нету синхронизации firefox с Хромом

Been using this for 1 year. Great for seperating your NSFW Accounts from SFW.
