SSL certificates not getting authenticated once firefox is upgraded to latest verrsion

Hi All,

  I have a desktop application that generates/updates the SSL certificates in browsers during its installation. The app was working fine till the FF browser was of version around 50. But, once the browser is upgraded, the app is not working properly. However, we are able to find out a work around for this by updating the SSL certificates with following configuration:
   req_extensions = v3_req
   [ v3_req ]
    subjectAltName = DNS:XXXX-localhost, DNS:XXXX-plugin
       After adding the above parameters we have to send the certificate to a signing authority and get it authenticated. Then the new certificate is imported into the browser using firefox browser options. Then the app starts working properly. Is there any alternative that we can do/follow to avoid this authentication process so that the app works in a smoothly.

Thanks & Regards

        Vikram
