Running Firefox 30.0. I am trying to add our internal root CA to be trusted by Firefox using command line. I ran this command: C:\temp\tools>certutil -A -n "Internal Certificate Authority CA" -t "CT,c,c" -i "cert1.cer" -d "C:\Users\myuserid\AppData\Roaming\Mozilla\Firefox\Profiles\72k9o7ll.default" After that succeeded, I ran this to verify it got added: C:\temp\tools>certutil.exe -L -d "C:\Users\myuserid\AppData\Roaming\Mozilla\Firefox\Profiles\72k9o7ll.default" Certificate Nickname Trust Attributes SSL,S/MIME,JAR/XPI DigiCert High Assurance CA-3 ,, GeoTrust SSL CA ,, Thawte SSL CA ,, VeriSign Class 3 Secure Server CA - G3 ,, DigiCert High Assurance EV CA-1 ,, VeriSign Class 3 Extended Validation SSL CA ,, Cybertrust Public SureServer SV CA ,, Internal Certificate Authority CA CT,c,c DigiCert SHA2 Extended Validation Server CA ,, Google Internet Authority G2 ,, GeoTrust SSL CA - G2 ,, Starfield Secure Certification Authority ,, Go Daddy Secure Certificate Authority - G2 ,, DigiCert SHA2 Secure Server CA ,, GlobalSign Extended Validation CA - SHA256 - G2 ,, RapidSSL CA ,, It's showing up on the list above but when I go to Firefox and open Tools ->Options->Advanced->Certificates->View Certificates->Authorities, I see a long list of certificates different than the one displayed above and my "Internal Certificate Authority CA" is NOT on the list. When I go to my internal sites protected with SSL issued by the internal CA, they are still not trusted. What am I missing? Thanks a lot.
