Details

List specific extensions that users cannot install in Microsoft Edge. When this policy is deployed, any extensions on this list that were previously installed will be disabled, and the user will not be able to enable them. If an item is removed from the list of blocked extensions, the extension is automatically reenabled anywhere it was previously installed.

Use ‘*’ to block all extensions that are not explicitly listed in the allow list.

If this policy is not configured, users can install any extension in Microsoft Edge.

Solution

Set the policy value for ‘Computer Configuration/Administrative Templates/Microsoft Edge/Extensions/Control which extensions cannot be installed’ to ‘Enabled’. A list of blocklisted extensions may then be specified.
