Mozilla::pkix module with stricter certificate verification is enabled in Firefox3 1 and later.

If you change the security system, Using _ Mozilla pkix _ verification in about:config is false. After restarting Firefox, the problem no longer appears, and it can be confirmed that the problem is caused by mozilla::pkix module. Please refer to the document [1][2] to check whether the certificate used by your company meets the new specifications.

In the future, Firefox will force PKIX to be enabled, and will not allow it to be disabled through a switch. It is recommended to refer to here to regenerate the self-signed certificate.
