I have a few internal web servers that are used to manage networking equipment. These web sites get this error. "Secure Connection Failed An error occurred during a connection to XXX. Issuer certificate is invalid. (Error code: sec_error_ca_cert_invalid)" I have added exceptions. did not change the symptom. If I revert to an older version of FF I have no problems. Obviously I would like to continue using FF but more and more of the things i do on my internal network are no longer working wth FF. It seems every update breaks something else i used to be able to do. Getting VERY old and Ive about had it. Please fix this.
