The extension recommendation messages may be disabled in an administrative policy by setting
the ExtensionRecommendations key under UserMessaging to false.
Rationale
The Recommended Extensions program recommends extensions to users as they surf the web.
The user must not be encouraged to install extensions from the websites they visit. Allowed extensions are to be centrally managed.
