This happens every time and is not a one-off. I'll be watching Rugby in full screen mode. I'll start an application on my PC that wants to use the Firefox browser as a front-end. When the new tab occurs and gains focus, I can not go back to full screen for the rugby game. The picture is about 3/4 of the window.
Now, I'm using my Samsung TV as a monitor if that has any bearing on this. It's strange and annoying as there is 1/3 of the bottom screen is black and about 1/4 on each side is black. The picture is centered and aligned to the top of the display.
If I try to go into full screen mode and back, the screen momentarily goes full screen and then it goes back to either the original, non-full screen, or the 2/3rds of the screen view.
Any ideas other than shutting down Firefox and restarting everything?
