I created a self-signed CA cert using openssl, and imported it into Firefox, but when I select it in the Certificate Manager under “Your Certificates” and click “View…”, I see the message “Could not verify this certificate because the issuer is not trusted.”

When I visit the site that I set up with an SSL cert signed by that same self-signed CA cert, I get an untrusted connection warning with the following technical details: “staging.cakemade.com uses an invalid security certificate. The certificate is not trusted because the issuer certificate is not trusted. (Error code: sec_error_untrusted_issuer)”

When I view the site certificate, it correctly identifies the issuer as the CA cert that I imported, but also displays the message “Could not verify this certificate because the issuer is not trusted.”

I am using Firefox Aurora, and apply updates daily. I am using the default settings for OCSP.

What do I need to do to get Firefox to trust the CA cert that I imported?

Chosen solution

I'm assuming you've imported your CA cert underneath the 'Authorities' tab. Restart FF after importing the cert.

I'd expect you're being prompted to set the trust level upon importing the cert. If not you can do that manually via the 'Edit Trust' button.

I had imported the CA cert under “Your Certificates.” I deleted the CA cert, switched to “Authorities”, re-imported the CA cert, and restarted Firefox. This fixed the problem.

Thanks for your help!
