I assume this is due to the increased security features in firefox 3, and the fact that the certificate Mike uses for the encryption only applies to "localhost" and not https://bbs.stardestroyer.net/. Of course, Firefox should give you an option to accept it anyway, which is why I'm submitting a bug report.bbs.stardestroyer.net uses an invalid security certificate.
The certificate is only valid for localhost.
(Error code: ssl_error_bad_cert_domain)
PS Mike, do you mind if I give a link to the secured forum when I post the bug on the publicly viewable Mozilla forums?
