Thanks to a fairly recent development, Referrer Policy, it's finally possible for websites to tell browsers to not leak referrers. It lets you specify a policy that's applied to all links clicked, as well as all other requests generated by the page (images, JS, etc.).
Is it possible for me to configure Firefox to never leak referrers, rather than relying each and every website to implement Referrer Policy?
