It doesn't work on Android
by Ali, 2024-12-24

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.
