  1. In Burp, go to the Proxy > Intercept tab. Click the Intercept is off button so it toggles to Intercept is on.
  2. Make sure you have checked that the proxy listener is active and have configured your chosen browser.
  3. With Burp running, open the browser that you configured and go to any HTTP URL (don't use HTTPS for the moment). Your browser should sit waiting for the request to complete, that is, it should look like it is stuck trying to load a page. This is because Burp has intercepted the HTTP request that your browser is trying to send.
  4. In Burp, go to the Proxy > Intercept tab. On the Intercept tab, you should see the intercepted HTTP request in the main panel.
  5. On the Proxy > Intercept tab the interception button says Intercept is on. If you click it, it will change to Intercept is off and the request will be released from Burp.
  6. Go back to your browser. You should now see the requested page loading as it would during normal browsing.

If everything went as described above, you have finished the mandatory configuration steps for using an external browser with Burp Suite. However, at the moment you will only be able to test web applications that exclusively use HTTP. If you try and access an HTTPS URL using your external browser, you will notice that the connection is blocked. Therefore, we strongly recommend that you perform the final additional step to install Burp's CA certificate so that you can also test applications using HTTPS.
