The big problem is that some firewalls strip Referer headers because they
don't want to reveal URLs of internal pages. For example, if
https://intranet.mozilla.com/Orbital_Mind_Control_Lasers.html links to
http://www.nasa.gov, Mozilla might not want nasa.gov administrators to see
that URL in their Referer logs. So Referer is not really fixable.
