HTTPS to HTTP, Header Location, Remove Referer, IE ok, But Firefox not

in IE case when I move from https to http via Header Location then referer erased
in Firefox case when I move from https to http via Header Location FF does not erase referer.
Maybe there is a special trick or command in PHP to make FF erase referer or some other trick?
Or headers like privacy policy, they are complicated....
