Don't work anymore

Didnt work.

Not working

Ne marche plus sur android

Won't work many times.

Youtube no longer supports the setPlaybackQuality API call which i assume this addon uses, so it no longer works.

Doesn't work on restart of firefox

Does not work in any version of the firefox browser.

did not actually work. videos still loaded at normal size and 360p despite my settings saying theater mode and 1080p

doesn't change videos to high resolution.

I've tried a every couple of months for past few years, never worked. I use stable branch.

Not working

Doesn't actually do anything to youtube videos.

Not work anymore, even update not helped

It doesn't work on Android

É simplesmente inútil. Coloquei na extensão para abrir vídeos do youtube como 1080p HD mas todo vídeo está abrindo como 720p mesmo tendo a poção de 1080p. É simplesmente inútil e um completo desperdício de espaço.

doesn't work and affect youtube at all, anymore
