Allowing Referer Headers

Using the default settings of including referring information may present a privacy/security risk. Requests to web pages may include this information as part of the HTTP Protocol and it tells what page you came from -- this additional information may also be used to track you.

The full list of available chromium switches is listed here under: "Don't send HTTP-Referer headers"
