Firefox full screen.

[Rikujin]

Hello people.

There is my problem.

When I'm watching videos from Youtube on Firefox app full screen, the screen is not fully fit. You can see on the picture black lines on both sides.

Is there some way to fit all the screen?

Maybe using about:config, will be possible, but I think on Android Is not possible.

Any suggestions?

Are you able to go full screen by placing a finger on each side of the display and swipe out each side @Rikujin

No.

I tried even with desktop site.
