After many concerns on other forums I'll add this now instead of later...
Why is the page blocked as unsafe?
That's the certificate I was referring to. You can click "I understand the risks" and add an exception to your certs.
It's safe.

Important! As of this posting Firefox 3 did warn of an invalid certificate because the Plugin Check isn’t final yet. Although, the site is safe. Mozilla will hopefully fix the certificate very soon.
