EC2 Load Balancer - installing CA Bundle SSL / intermediate certificate

I am using the EC2 Load Balancer to handle HTTPS requests. For Chrome & Safari, having the Load Balancer Protocol set HTTPs at Port 443 with the the SSL cert handles most traffic correctly. HTTPS requests from Safari & Chrome are fine. However in Firefox, I get the connection is insecure "(Error code: sec_error_unknown_issuer)." In checking with a cert checker, I get The certificate is not signed by a trusted authority (checking against Mozilla's root store). If you bought the certificate from a trusted authority, you probably just need to install one or more Intermediate certificates. In talking with my cert provider, the information I got was : As we can see certificate has been installed improperly at the server. There is no CA bundle at the server that is why browsers may show warning messages. How do you install a CA Bundle using the Load Balancer?
