rel=noreferrer

{{HTMLSidebar}}

The noreferrer keyword for the rel attribute of the {{HTMLElement("a")}} , {{HTMLElement("area")}} , and {{HTMLElement("form")}} elements instructs the browser, when navigating to the target resource, to omit the {{HTTPHeader("Referer")}} header and otherwise leak no referrer information — and additionally to behave as if the noopener keyword were also specified.
