Do you possibly have this root certificate installed in Firefox ?

Does it work if you install this certificate in Firefox and set the trust bit to make it work as a rot certificate ?

  • Options/Preferences -> Privacy & Security
    Certificates: View Certificates

No. This root certificate not installed in FF Yes. If install our root cert in FF site on start FF working fine. But! I don't want use FF cert storage (security.enterprise_roots.enabled;true). In Windows cert storage this cert is installed via AD. When refreshing this page after 10-12 sec after start it's work fine. but on starting FF i have SEC_ERROR_UNKNOWN_ISSUER
