pecific preferences/settings

###  Firefox preferences

You can configure the _default_ referrer policy in Firefox preferences. The
preference names are version specific:

  * Firefox version 59 and later: ` network.http.referer.defaultPolicy ` (and ` network.http.referer.defaultPolicy.pbmode ` for private networks) 
  * Firefox versions 53 to 58: ` network.http.referer.userControlPolicy `

All of these settings take the same set of values: ` 0 = no-referrer ` , ` 1 =
same-origin ` , ` 2 = strict-origin-when-cross-origin ` , ` 3 = no-referrer-
when-downgrade ` .
