Mozilla Firefox tweaks Referrer Policy to shore up user privacy

Firefox 87, due to ship on March 23, will cut back on path and query string information from referrer headers "to prevent sites from accidentally leaking sensitive user data."

"Firefox will apply the new default Referrer Policy to all navigational requests, redirected requests, and subresource (image, style, script) requests, thereby providing a significantly more private browsing experience," Firefox says.
