Garbled text at end of proxy intercept - no username/pass

Hi, running a proxy on 127.0.0.1 as suggested, I'm getting: POST / HTTP/1.1 Host: ocsp.sca1b.amazontrust.com User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:66.0) Gecko/20100101 Firefox/66.0 Accept: */* Accept-Language: en-US,en;q=0.5 Accept-Encoding: gzip, deflate Content-Type: application/ocsp-request Content-Length: 83 Connection: close 0Q0O0M0K0I0 + Although it looks like the garbled stuff isn't parsing correctly here. Here's a screenshot, where I think the username/pw info should be: https://imgur.com/a/c2wLPzs Is this a java issue? Or what is causing this? Happens on all sites.

It's actually not intercepting sites correctly either - for example going to Instagram doesn't even show instagram URls.

What you've sent a screenshot of is an OCSP request, which is part of your browser's certificate validation process. If you keep forwarding requests you will see the ones you expect afterwards. I recommend you disable Intercept while you're getting used to Burp. I generally have Intercept turned off and only turn it on for specific circumstances where I need it.
