Maybe I'm missing something, but we need a way to completely turn off Themes in the extension. What with Firefox themes, Youtube's light/dark modes, and the settings of the essential Dark Reader, none of the "Improve Youtube" themes and night mode combinations of settings I've tried (many) provides a comfortable, readable display of www.youtube.com/feed/subscriptions or www.youtube.com/feed/channels in dark mode. Could be an alpha channel or blending mode mistake.
Maybe the "just right" setting could be found by digging into the documentation, but I haven't found this yet, and anyway, an extension is not an application and every setting should be described right next to the corresponding control or in a hover/right-click popup bubble.

I think I got stuck in some youtube experiment and the whole site have changed and this addon doesn't work with anything anymore. If anyone knows how to opt out of experiments...

The site is unusable without this.

FINALLY I CAN TURN OFF YOUTUBE MIXES ON MUSIC VIDEOS!!! THANK YOU SO MUCH!!! It is still there on the sidebar as an OPTION if I WANT TO WATCH IT, because these developers understand consent UNLIKE YOUTUBE. THANK YOU SO MUCH!!!

The blocking feature, which is the reason I installed it, doesn't work. Youtube keeps recommending me channels that I've told it 500 times I don't want to see again. Also I keep getting shorts on channel pages, so that's another feature that just doesn't work.

Ability to loop YT videos with switched off screen on Android is unparalleled with this extension. Thank you

Thank you thank you :) I can finally get rid of all these stupid changes youtube is forcing down our throats

doesn't work on mobile .-.
