As of Firefox 45 we intend to turn referrerpolicy attribute on by default on all platforms. It has been developed behind the network.http.enablePerElementReferrer preference. Other UAs shipping this or intending to ship it are Chrome and Opera [1].
The referrerpolicy attribute as specified in the referrer policy spec allows per element referrer policies for <a>, <area>, <img>, and <iframe> tags. Referrer policies allow to specify which referer [sic] header is sent when performing the request. The referrerpolicy attribute allows developers to override the document's referrer policy (set in meta tag or via CSP) on a per element basis. This feature was previously discussed in this "intent to implement" thread: https://groups.google.com/d/topic/mozilla.dev.platform/g-YY5rWFCLM/discussion. *Bug to turn on by default*: https://bugzilla.mozilla.org/show_bug.cgi?id=1223838 *Link to standard*: https://w3c.github.io/webappsec-referrer-policy/ [1] https://www.chromestatus.com/feature/5743723954569216 _______________________________________________ dev-platform mailing list [email protected] https://lists.mozilla.org/listinfo/dev-platform
