Following this question -> Why are HTTPS requests blocked by Firefox when using ZAP proxy?
I was looking in Burp Suite where I could generate its CA for Firefox. I could not see it. I went to Burp website -> https://support.portswigger.net/customer/portal/articles/1783087-installing-burp-s-ca-certificate-in-firefox but they show a url http://burp
which is not working on my browser.
Where can I generate Burp's certificate?
