New Window Setup allows you to setup where will Firefox create new windows - on which monitor and with what size.


  • Firefox creates new window on the same monitor where the last focused window is. If you use multiple monitors and you have Firefox windows opened on each one, new window can be created on any of them. Using this addon you can force it to a specific monitor.
  • Firefox creates new windows with the same size as the last focused window. If your last focused window is snapped on a side, your new window will have this crazy size.
Using this addon your new windows will be always on the correct monitor with the correct size!
