Hello,

Please see the article "This Connection is Untrusted" error message appears - What to do. It could be a corrupt cert8.db file, please follow the steps in https://support.mozilla.org/en-US/kb/connection-untrusted-error-message#w_the-certificate-is-not-trusted-because-the-issuer-certificate-is-unknown

You may also want to check your antivirus/firewall settings. If you are using Avast, the latest Firefox release (version 33.1 released yesterday) fixes an issue with HTTPS Scanning. Your user agent shows 33.0.3 - you can update by going to:

  • Help (or New Fx Menu > Help-29 ) > About Firefox

I've tried all the listed fixes, which includes the one you posted. NONE of them have worked. I'm also using Kapersky and that doesn't seem to be the issue. Thx though.
