Developer’s Description
Control what gets sent as the HTTP Referer on a per-site basis. You create a list of sites, and the referrer that should be sent for each site. You can choose to send that referrer unconditionally or only for third-party requests. Additionally, you can specify the default behavior for any site not in the list.
