In about:config, setting 'network.http.sendRefererHeader' to 0 (default is 2) will stop the referer header from being sent, and the document.referrer from being set. See http://kb.mozillazine.org/Network.http.sendRefererHeader http://kb.mozillazine.org/Network.http.sendRefererHeader for more information.

Disabling the referrer header completely can prevent you from signing into some sites unfortunately. Another option in Firefox is to use network.http.referer.spoofSource. In the URL bar, type: about:config Search for the following setting: network.http.referer.spoofSource Double-click to set its value to true. This basically sends the destination or target URL as the referrer.

  I have not had issues thus far signing in on sites, though that might just have been dumb luck. I appreciate the heads-up and the additional information, thanks!

There are several referer settings. https://raw.githubusercontent.com/pyllyukko/user.js/master/user.js https://raw.githubusercontent.com/pyllyukko/user.js/master/u... user_pref("network.http.referer.userControlPolicy", x); // TODO: https://github.com/pyllyukko/user.js/issues/94 https://github.com/pyllyukko/user.js/issues/94, commented-out XOriginPolicy/XOriginTrimmingPolicy = 2 prefs user_pref("network.http.referer.spoofSource", x); user_pref("network.http.referer.XOriginPolicy", x);

  uMatrix also has a similar feature, among many others (request blocking by type, cookie and cache management, etc...) https://github.com/gorhill/uMatrix https://github.com/gorhill/uMatrix

That page is quite outdated (2007), a better reference for about:config referrer options is https://wiki.mozilla.org/Security/Referrer https://wiki.mozilla.org/Security/Referrer (which is linked to at the bottom of the blog post about FF59 being discussed). It seems that Firefox 59 will effectively force about:config's network.http.referer.XOriginTrimmingPolicy to 2 (default is 0) when in private browsing.

Similar for Chrome, there's a flag at chrome://flags/#reduced-referrer-granularity Description: "If a page hasn't set an explicit referrer policy, setting this flag will reduce the amount of information in the 'referer' header for cross-origin requests."
