Need this extension badly for firefox fenix as on youtube mobile site videos in landscape mode are cut out/cropped/zoomed and works correctly when setting user agent to android 7 and below, means youtube loads differently on android 8 and above causing this issue. Hope you can bring it to fenix.

Work fine!
I use it to regain OLD YouTube layouit and keep my userscripts / Addons working on it.

Wonderful

Youtube 'old layout' army incoming ;-)
