It doesn't work

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.

Most needed functions are paywalled. Some are not (hence the second star). Seems too bloated If you just want to use the free options -- frequently you stumble upon something that only works when you pay money.
Would use a clone of this with just the free options -- it probably would deserve at least 4 stars.

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

Одна папка и посылают нах

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 :)
