We have deployed a certificate created by an internal Windows CA on a tomcat web site. When we use IE to browse to the site the page loads without issue. When we use Firefox we get : This Connection is Untrusted and under technical details: site.name:port uses an invalid security certificate. The certificate is not trusted because the issuer certificate is not trusted. (Error code: sec_error_untrusted_issuer) Any idea why?

FF doesn't know about your internal Windows CA. It therefore treats the cert issued by your CA as untrusted.
Get a cert for your site from a CA which already is listed in the FF certificate store.

Is there way way to make FF aware of our internal Windows CA enterprise wide?

You will have to export the certificate in IE and import the certificate in Firefox or otherwise install the certificate in Firefox.
