It helped remove the black bar in full-screen mode on the smartphone.

+ It would be nice if you could add to the description what else this plugin fixes, please.

It did exactly what I was looking for! It fixed my issue with m.youtube.com where the video player doesn't go fully fullscreen and left a gap below.

This actually fixed the black bar at the bottom of every YouTube video I watch! Thank you so much to whoever made this

It worked. Fullscreen works properly. Thank you
