This Connection is Untrusted You have asked Firefox to connect securely to st1x.cdnfile.info, but we can't confirm that your connection is secure. 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 st1x.cdnfile.info uses an invalid security certificate. The certificate is only valid for the following names: *.vidcloud9.com, vidcloud9.com Error code: SSL_ERROR_BAD_CERT_DOMAIN 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. Explain why this is still happening
