→Importing a Root Certificate
'''Important:''' Deleting a root certificate that is in the default root store is equivalent to turning off all of the trust bits for that root. Therefore, even though the root certificate will re-appear in the Certificate Manager, it will be treated as though you changed the trust bits of that root certificate to turn them all off.
== Untrusted Connection Error Messages ==
When you visit a website whose web address starts with https, your communication with the site is encrypted to help ensure your privacy. Before starting the encrypted communication, the website will present Firefox with a [[CA:FAQ#What_are_certificates.3F | certificate]] to identify itself. The certificate helps Firefox determine whether the site you're visiting is actually the site that it claims to be. If there is a problem with the certificate, you will see the [https://support.mozilla.org/en-US/kb/connection-untrusted-error-message This Connection Is Untrusted] alert page.
