Help install certificates Ubuntu 10.04

Forgive me if this is not the correct place to post my questions.

I am a complete newbie with this. I purchased PositiveSSL Certificate and received it.
I followed the install page “Certificate Installation: Apache & mod_ssl”.

I am also using dyndns to point to my server.

When I type I get the following in Firefox: Unable to connect
Firefox can’t establish a connection to the server at

I can connect this way:

Is there anyway to help me find out what I am doing wrong?

There seems to be a .pem file that is used if I want to have SSL Encryption for users. Is that something I need and where do I, or how do I generate that?

thanks for any help you can offer.
