I downloaded burp, setted up proxy on firefox and I added CA certificate to authorities, but i got error MOZILLA_PKIX_ERROR_MITM_DETECTED or sometimes other, but I don't remember name of it. I chceked everything. I reinstalled firefox, burp and certificate, I refreshed my browser, also I refreshed SSL/TLS security in my anti-virus, which is eset security, but nothing works. Still the same problem and I don't have more ideas and I'm losing hope. Someone know what else I can try? Also after setting up proxy in firefox, with intercept on I don't get "infinite" loading page when I', refreshing new window.

Thanks for your message. When you imported the CA certificate into Firefox did you edit the trust settings and select "This certificate can identify websites"? https://portswigger.net/burp/documentation/desktop/getting-started/proxy-setup/certificate/firefox
