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

Is not currently working on mobile Firefox Nightly.

Doesn't actually do anything to youtube videos.

Not work anymore, even update not helped

It doesn't work on Android

Doesn't seem to apply preferred resolution setting. Also the "auto play next video" setting didn't actually play the next video. On one page, the settings it was applying to change the video player size glitched out and the page was all wonky; I had to refresh for it to fix.

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.

খুব ভালো।
