Do you see the certificate under Authorities? Tools > Options > Advanced > Encryption: Certificates > View Certificates : Authorities

Did you set the trust bit(s) of that certificate to make Firefox trust the as a root certificate? Otherwise Firefox wont' trust the certificate.

You can also check the certificate chain by clicking the globe/padlock on the location/address bar to see if this certificate is included.
