It's been working great for my purposes until just a few minutes ago, the logo has become black and clicking on it says 404 not found. I tried disabling and re-enabling it, but to avail. Prolly needs a quick update (no updates showing right now) and it'll be up and running again. Recommended.

Used to work perfectly but just updated today and now I can't disable 60fps or anything because everything is "Coming Soon"

Shouldn't release an update to an add-on like this unless the extension is working! Especially since I currently can't find a working alternative in the meantime.
Guess I'll have to watch all the 60fps videos in 480p now...

Edit: Oh, okay, thank you!

Installed this to get reverse playlists. The setting is there but the button doesn't show up.

Crap

lag and bug

This app is working as intended, you just need to head to the iridum's settings and enable autoplay. The app works after that.

This addon makes YouTube a lot more usable. I love the blacklist feature, the ability to disable autoplay, and ad control.

Видео на YouTube вообще перестали включаться после установки этого приложения. Как только удалил - всё опять заработало. правьте. Пока удаляю. Win 7 x64, Firefox 68.0.1 (32bit)

Had good ideas but it's pretty much abandonware now.

Prevent videos from playing. ANY videos.

Made YouTube stop playing ANY video.

It was a decent replacement for Youtube Plus and the old Youtube Center, but the dev stopped updating it since Jan 2019. Now YT videos don't load anymore and the extension's settings are unreachable.
