YouTube High Definition에 대한 리뷰 – Firefox Android용 부가 기능 (ko)

not working as of 2026.06.25

Doesn't work anymore

Just doesn't work. Not on shorts or full videos, quality still rubbish and defaulting to auto or low despite decent internet and using this extension with all permissions allowed.

Doesn't do anything, YouTube keeps picking quality by itself

Works as expected, except when theater mode doesn't work.

Constantly asks for permissions to read/change data on all websites and puts a green dot on the UI about it.

There's no reason it needs permissions to read/change data on all websites, but yet it asks for it...

For some reason it keeps switching to normal mode instead of theater, even when I ask it to stay in theater mode. Other than that, pretty great!

Thank you for adding this extension. It has a feature Google refuse to implement. It is so stupid how Youtube doesn't let you set a preferred resolution

It used to work fine a year ago. Now it's not working correctly :(
