The Referrer-Policy HTTP header governs which referrer information, sent in the Referer header, should be included with requests made.

Header type Response header
Forbidden header name no


Note that Referer is actually a misspelling of the word "referrer". The Referrer-Policy header does not share this misspelling.

Referrer-Policy: no-referrer
Referrer-Policy: no-referrer-when-downgrade
Referrer-Policy: origin
Referrer-Policy: origin-when-cross-origin
Referrer-Policy: same-origin
Referrer-Policy: strict-origin
Referrer-Policy: strict-origin-when-cross-origin
Referrer-Policy: unsafe-url


The Referer header will be omitted entirely. No referrer information is sent along with requests.
no-referrer-when-downgrade (default)
This is the user agent's default behavior if no policy is specified. The URL is sent as a referrer when the protocol security level stays the same (HTTP→HTTP, HTTPS→HTTPS), but isn't sent to a less secure destination (HTTPS→HTTP).
Only send the origin of the document as the referrer in all cases.
The document https://example.com/page.html will send the referrer https://example.com/.
Send a full URL when performing a same-origin request, but only send the origin of the document for other cases.
A referrer will be sent for same-site origins, but cross-origin requests will contain no referrer information.
Only send the origin of the document as the referrer to a-priori as-much-secure destination (HTTPS→HTTPS), but don't send it to a less secure destination (HTTPS→HTTP).
Send a full URL when performing a same-origin request, only send the origin of the document to a-priori as-much-secure destination (HTTPS→HTTPS), and send no header to a less secure destination (HTTPS→HTTP).
Send a full URL when performing a same-origin or cross-origin request.
This policy will leak origins and paths from TLS-protected resources to insecure origins. Carefully consider the impact of this setting.

  • From version 53 onwards, Gecko has a pref available in about:config to allow users to set their default Referrer-Policy network.http.referer.userControlPolicy.
  • From version 59 onwards (See #587523), this has been replaced by network.http.referer.defaultPolicy and network.http.referer.defaultPolicy.pbmode.

Possible values are:

  • 0 — no-referrer
  • 1 — same-origin
  • 2 — strict-origin-when-cross-origin
  • 3 — no-referrer-when-downgrade (the default)
