Smart Referer

Improve your privacy by limiting Referer information leak!

What is Smart Referer?
"Smart Referer" is a Firefox add-on that enhances your online privacy. It works by automatically hiding HTTP Referer and JavaScript document.referrer during cross-domain requests, which can reduce information leakage during web browsing. To prevent any potential site breakage, a regularly updated whitelist of related domains is applied in the background. This extension is also compatible with Waterfox Classic.
