Configure extension installation allow list

Setting the policy specifies which extensions are not subject to the blocklist.

A blocklist value of * means all extensions are blocked and users can only install extensions listed in the allow list.

By default, all extensions are allowed. But, if you prohibited extensions by policy, use the list of allowed extensions to change that policy.

Example value:

extension_id1
extension_id2

Supported on: At least Microsoft Windows 7 or Windows Server 2008 family

Extension IDs to exempt from the blocklist

Registry HiveHKEY_CURRENT_USER
Registry PathSoftware\Policies\Google\ChromeOS\ExtensionInstallAllowlist
Value Name{number}
Value TypeREG_SZ
Default Value

chromeos.admx
