When a firefox window spans two displays with different resolutions, we draw the hamburger menu's pop-up at the wrong resolution.

See attachment, where Firefox is mostly on my macbook's native retina display, but part, including the hamburger are on an external 27" display driven at 2560x1440. Clicking on the popup renders the menu at too high a pixel density, and it doesn't fit inside the calculated bounds.
