Firefox window menu options on Mac
I've recently started working with a Mac (Catalina) and found an oddity that only seems to apply to Firefox. I set up keyboard shortcuts for moving windows between my macbook display and an external monitor using the in-built keyboard options to add shortcuts.
These target the Window>Move to [DISPLAY NAME] menu entries at the top of the screen. For some reason Firefox windows don't have this menu entry and therefore my shortcuts don't move Firefox windows between my screens.
I've included a couple screenshots to demonstrate. It's not a huge deal but I wonder if it's an issue with my machine or just a quirk of Firefox?
