Need to use an application that utilises an authentication via a certificate (mutual TLS). I have looked an importing this on the burp tool but not had any success. The easiest option for me is to configure the browser's proxy setting to match the one with burp and login the conventional way then toggle the intercept once I've logged in successfully however I'm getting a number of issues setting this up. On the proxy listeners section it fails to start proxy service on 127.0.0.1:8080. I've changed the port number to 8085 and this starts the proxy service in burp I then match the settings on the browser (Firefox), however unable to connect any websites and I believe it doesn't trust the certificate? I then looked an installing Burp's CA certificate, however when doing so i get an error stating that "This is not a certificate authority certificate, so it can't be imported into the certificate authority list". Please can somebody help me with this as this has all worked before? Not sure if's down the the current release. Burp version v2022.3.6
