This is a server bug. The websites certificate is signed by a Geotrust intermediate, and that certificate must be provided by the server too. Adding the missing intermediate manually also works, but in any case, this isn't a Firefox bug.

Firefox 6.0.2 on Ubuntu 11.04 shows this as untrusted and no certificate chain is shown. The same version of Firefox running under Windows 7 has no problem with the certificate and the full certificate chain is shown. This is a problem because users will not trust the Checkout page for a vendor which has a valid certificate, or (worse) will assume that invalid certificates are OK to accept.
