We have a self hosted live help program. Its on a sub-domain of our main website's domain: IE: support.mysite.com. The live help link is called using javascript link. Now, we are trying to get the link to work on both the SSL pages and the non-ssl pages. Both domains have a ssl certificate, although from different signers. In firefox, we get the nasty "Website Certified by an Unknown Authority" error, even though we are calling the javascript link from https://support.oursite.com, on a secure page. Now, what I'm trying to figure out is whether Firefox doesn't like seeing ssl certificates from 2 domains, or they don't like the certificate itself. Is there any way to differentiate between the two situations. Internet Explorer works perfectly so I cant test with it. Any help would be appreciated.
