Information
This setting allows the configuration of how Firefox handles scripts from moving or resizing browser windows.
The recommended state for this setting is: Enabled
Arbitrary web sites can disguise an attack taking place in a minimized background window by moving or resizing browser windows.
Solution
To establish the recommended configuration via GP, set the following UI path to Enabled :
Computer Configuration\Policies\Administrative Templates\Mozilla\Firefox\Preferences (Deprecated)\dom.disable_window_move_resize
Note: This Group Policy path does not exist by default. An additional Group Policy template ( firefox.admx/adml ) is required - it is available to download at this
link
.
Impact:
Scripts will not be able to move or resize browser windows.
