Why do other browsers ( IE, Chrome, Opera,Safari) list StartCom Class 2 Primary Intermediate Server CA as a Trusted Intermediate Certification Authority but Firefox doesn't?

We are setting up registrations for a paid event and have bought a SSL certificate for our site. Everything works fine when the registration page is accessed through IE, Chrome, Opera or Safari (which list StartCom Class 2 Primary Intermediate Server CA as a Trusted Intermediate Certification Authority), but when I click on that link in Firefix I get the "This Connection is Untrusted" page because only StartCom Class 1 is listed as trusted.


Why is that?

It is always the responsibility of a website to send the complete certificate chain.

You can check the certificate chain of breastfeedingconference.asn.au and see that the server doesn't send the intermediate certificate.
