I had to resolve the issue by deleting the certificate entirely both CRT and Activation and then re-installing the Certificate using the CA-Bundle from the Certificate Authority.

I encountered an issue where the SSL Chain was broken and it was only Firefox that displayed the Untrusted Connection warning but it was only if Firefox had not previously cached the Intermediate Certificates from another website. If you can also point me to technical documentation from Microsoft and/or Google that confirms this that would help as well. I don't see technical documentation regarding this issue so your help is appreciated. It may have something to do with the caching of certificates or it may be as I have described below.

I am attempting to document why Firefox displays a warning while Chrome and Internet Explorer do not. Can someone please confirm the following for me? Or make any corrections? I want the information that I document to be completely accurate. I am attempting to document an issue that I recently encountered.
