I've installed burp, and set up a listener, according to the instructions here: http://portswigger.net/burp/help/suite_gettingstarted.html
I'm now trying to configure firefox to use the burp listener as a proxy. I've followed the instructions on that page. The only difference between the documentation and how I've set things up is that I've used a slightly different path to get to the proxy settings. (edit->preferences->advanced->network)
I've set the http proxy to 127.0.0.1:8080, in accordance with the docs.
When I send a request, the first request gets to the burp listener. But when I let it through, I see this in the firefox pane
Burp proxy error: Can't connect to SOCKS proxy:127.0.0.
I've looked very closely at my config. I'm absolutely certain that I haven't dropped the '1'.
What could be going wrong here?
you should put a tick before "Use SOCKS proxy",see below enter image description here
and then,add "1" behind "127.0.0." and add "0" behind "108" enter image description here
last,put a tick before "Use SOCKS proxy" again,and it will be okay enter image description here
