Discussion

Malicious websites often try to confuse or trick users into giving a site permission to perform an action allowing the site to take control of the users' computers in some manner. Disabling or not configuring this setting allows unknown websites to: - Create browser windows appearing to be from the local operating system. - Draw active windows displaying outside of the viewable areas of the screen capturing keyboard input. - Overlay parent windows with their own browser windows to hide important system information, choices, or prompts.
