Configure extension management settings

Supported versions

On Windows and macOS since 77 or later

Description

Setting this policy controls extension management settings for Microsoft Edge, including any controlled by existing extension-related policies. This policy supersedes any legacy policies that might be set.

This policy maps an extension ID or an update URL to its specific setting only. A default configuration can be set for the special ID "*", which applies to all extensions without a custom configuration in this policy. With an update URL, configuration applies to extensions with the exact update URL stated in the extension manifest. If the 'override_update_url' flag is set to true, the extension is installed and updated using the update URL specified in the ExtensionInstallForcelist policy or in 'update_url' field in this policy. The flag 'override_update_url' is ignored if the 'update_url' is the Edge Add-ons website update URL. For more details, check out the detailed guide to ExtensionSettings policy available at https://go.microsoft.com/fwlink/?linkid=2161555.

To block extensions from a particular third party store, you only need to block the update_url for that store. For example, if you want to block extensions from Chrome Web Store, you can use the following JSON.

{"update_url:https://clients2.google.com/service/update2/crx":{"installation_mode":"blocked"}}

Note that you can still use ExtensionInstallForcelist and ExtensionInstallAllowlist to allow / force install specific extensions even if the store is blocked using the JSON in the previous example.

If the 'sidebar_auto_open_blocked' flag is set to true in an extension's configuration, the hub-app (sidebar app) corresponding to the specified extension will be prevented from automatically opening.

On Windows instances, apps and extensions from outside the Microsoft Edge Add-ons website can only be forced installed if the instance is joined to a Microsoft Active Directory ___domain or joined to Microsoft Azure Active Directory®`.

On macOS instances, apps and extensions from outside the Microsoft Edge Add-ons website can only be force installed if the instance is managed via MDM, joined to a ___domain via MCX.
