Our company has an AD environment. So our internal web site use the self-signed certificate. The root certification is our AD certification. When i access our internal web site, it will show :sec_error_unknown_issuer". If i import the root certification into firefox, the issue will been resolved.

However, the number of computers there are more than five hundred. Do you have any quick way to import the root certificate? Or other function to resolve my question?
