because of changes in firefox: "Remote XUL (XUL through HTTP) has been removed from Firefox 4 (see bug 546857 for more information). But there's still a whitelist that allows remote XUL access on a per-domain level
To allow the xul demos from bugzilla's attachments directly, you need https://addons.mozilla.org/en-US/firefox/addon/remote-xul-manager/ then add https://bugzilla.mozilla.org/ to that xul-whitelist.
to allow local file://xul in current FF, goto about:config and set dom.allow_XUL_XBL_for_file -> true
