Windows 10, window grabbing between tabs and window controls stops working only on third monitor

more options

So are you using userChrome.css or theme other then what available default for Firefox? When using more then on monitor if there is issue that is more related to the O/S and GPU driver and how they determine what display on what and what functions are used in each monitor.
