I decided that I needed to put in a trouble ticket and clicked on the appropriate link. FireFox said:

This Connection is Untrusted











You have asked Firefox to connect
securely to www.ubbcentral.com, but we can't confirm that your connection is secure.
_____________


Normally, when you try to connect securely,
sites will present trusted identification to prove that you are
going to the right place. However, this site's identity can't be verified.



What Should I Do? [Firefox asked that]



If you usually connect to
this site without problems, this error could mean that someone is
trying to impersonate the site, and you shouldn't continue.



Technical Details


www.ubbcentral.com uses an invalid security certificate.

The certificate is not trusted because the issuer certificate is unknown.

(Error code: sec_error_unknown_issuer)


I Understand the Risks


If you understand what's going on, you
can tell Firefox to start trusting this site's identification.
Even if you trust the site, this error could mean that someone is
tampering with your connection.



Don't add an exception unless
you know there's a good reason why this site doesn't use trusted identification.
