Wrong origin for menu windows in the toolbar
Since several version of Firefox, I'm unable to use the menu of Firefox when in full screen as it shows itself outside of screen. As I understand it, the origin of the windows seems not correct, as the arrow on the top, which should be under the mouse pointer, is at the opposite. (See the picture attached, it's probably best explained that way).
I've tried to launch Firefox in safe mode, but It didn't change anything.
