http://bugzilla.mozilla.org/bug_status.html links to http://bugzilla.mozilla.org/confirmhelp.html but this document doesn't exists. The link is activated when the "UNCONFIRMED" text is clicked. /confirmhelp.html is a standard document of any bugzilla installation ( http://open-site.org/code/bugzilla/confirmhelp.html for example). Either it's put on bugzilla.mozilla.org as well, or the link is removed from bug_status.html IMO.

After digging up, it seems confirmhelp.html has been marked as dead and eliminated from the CVS. So what's required in order to eliminate the 404 link is to update http://bugzilla.mozilla.org/bug_status.html with the latest version, found out for example at http://landfill.bugzilla.org/bugzilla-tip/bug_status.html .

This is already fixed in Bugzilla. b.m.o will pick it up in the next upgrade (which should be shortly after we move to the new servers) *** This bug has been marked as a duplicate of 194744 ***
