This is the message:This Connection is Untrusted You have asked Firefox to connect securely to www.savesfbay.org, 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? 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.savesfbay.org uses an invalid security certificate. The certificate is not trusted because the issuer certificate is unknown. (Error code: sec_error_unknown_issuer) Save the Bay last week updated their Security Certificate. What bothers me is that this message does not pop up on my housemate's computer (also a Mac) and Save the Bay also attempted to duplicate that message on a number of computers but couldn't.
