I HAVE DUAL COMPUTER MONITORS AT MY WORKPLACE - EVER SINCE THEY UPDATED MY FIREFOX BROWSER FROM VERSION 28 TO VERSION 46.0.1, WHEN I RIGHT CLICK A LINK AND CHOOSE "OPEN PAGE IN NEW WINDOW" IT WILL ONLY OPEN UP THE WINDOW ON MY LEFT MONITOR.. NORMALLY IT WOULD DO THIS AND AFTER A FEW TIMES OF MY MANUALLY MOVING THE WINDOW TO MY SECOND MONITOR, IT WOULD AUTOMATICALLY OPEN IN MY SECOND MONITOR FROM THEN ON OUT... WHAT CAN I DO TO GET IT TO START DOING THIS AGAIN? ITS SERIOUSLY SLOWING DOWN MY PERFORMANCE TO HAVE TO MOVE IT MANUALLY EVERY SINGLE TIME.. I DO IT 100'S OF TIMES A DAY...
