Hi rahulparmar,

I understand that the warning "The Connection is Untrusted" is showing up. It is possible for the users to add an exception: "This Connection is Untrusted" error message appears - What to do

However since they are self signed, it is also possible to check to make sure that they follow the guidelines for:

For specific debugging errors we are happy to help or refer to the certificates@mozilla.org address.

If it works with other browser then check the certificate chain and see if you can export a trusted root certificate. Then you can import this certificate in Firefox and set the appropriate trust bits when prompted.

Do you see the certificate under Authorities? Tools > Options > Advanced > Encryption: Certificates > View Certificates : Authorities

Did you set the trust bit(s) of that certificate to make Firefox trust the as a root certificate? Otherwise Firefox wont' trust the certificate.

You can also check the certificate chain by clicking the globe/padlock on the location/address bar to see if this certificate is included.

Does the CA certificate follow the guidelines? Disabling this policy in Firefox would cause serious security issues. If absolutely necessary see:https://support.mozilla.org/en-US/que.../1012765

Note that disabling libPKIX support via security.use_mozillapkix_verification = false only applies to Firefox 31 and 32, so that is no longer possible in current releases.
