link check for mozilla.org fails with 404

Please have a look at <http://bugzilla.mozilla.org/show_bug.cgi?id=80122>

Seems like your link checker allways displys 404 errors for mozilla.org's
pages, even if they exist for a normal browser.

Who is in error? Is http://www.mozilla.org replying wrong http: answers or
do you ask it the wrong question?
