1.1.24 Ensure 'Allows a page to show popups during its unloading' is set to 'Disabled'

Information

This policy setting controls whether popups show during page unloading in Microsoft Edge.

The recommended state for this setting is: Disabled.

Rationale:

Allowing popups during page unloading can allow a page with a vulnerability to exhaust system resources through popups or introduce malware onto the system if clicked.

Impact:

None - this is the default behavior.

Solution

To establish the recommended configuration via GP, set the following UI path to Disabled

Computer Configuration\Policies\Administrative Templates\Microsoft Edge\Allows a page to show popups during its unloading

Note: This Group Policy path may not exist by default. It is provided by the Group Policy template MSEdge.admx/adml that can be downloaded from Microsoft here.

Default Value:

Disabled.
