Why would Firefox give me an "Untrusted Connection" error where IE and Chrome don't?

I get an Untrustead connection error in Firefox when accessing https://eponline.mom.gov.sg/epol/. Both IE and Chrome trust the site. What's different about Firefox?

This Connection Is Untrusted error message may appear when trying to visit secure (https) websites in Firefox.

It Appears in Google Chrome also..

The eponline.mom.gov.sg server doesn't send a required intermediate certificate.

You can inspect the certificate chain via a site like this:

You can install the Entrust Certification Authority - L1C by copying the certificate text to a .cer text file and import that file in the Certificate Manager.
Do not check off any trust bits, those are only required for a root certificate and not for an intermediate certificate.
