Please note that this extension has been largely superseded by better browser defaults for websites using HTTPS (almost all) and is not maintained anymore. Automatically hide HTTP Referer and JavaScript document.referrer for cross-domain requests! To workaround (rare) breakage, a whitelist of related domains is regularily downloaded (24h) and applied in the background. You may view and update the current version of this whitelist here. Further information on advanced configuration options, writing your own whitelist entries and contributing is available in the repositiory README file. This extension supports Waterfox Classic!
