I have a local only test ca and test web server. How do I load the CA certificate into Firefox. Adding it via "settings" did not work, the browser says Adding a root via "settings" does nothing. When I access a web server it says "the original certificate provided by the server is untrusted", in the issuer name field. It never actually shows the certificate. Adding a file to the appdata area (this is on windows 10) also fails; changing the enterprise ca settings does not work. This used to work.
