Burp Suite

I am trying to intercept requests in burp suite but it is not intercepting but all other website apart from hackthebox machines are intercepting plz give me solution for this please pm me on this

Same problem here, I tried to add pac also/foxy proxy and same results. Any idea?

It’s very likely that you either did not import the certificate or did not configure the proxy correctly. Make sure to fully follow the guide here Configuring Firefox to work with Burp - PortSwigger. Or, check youtube videos that walk you through the process
