To test applications in your own browser over HTTPS, you need to install Burp Suite's CA certificate.

Note

These steps are only necessary if you want to use your own external browser for manual testing with Burp. If you prefer, you can just use Burp's browser, which is preconfigured to work with Burp Proxy already. To access Burp's browser, go to the Proxy > Intercept tab, and click Open Browser.

Before attempting to install Burp's CA certificate, make sure that you have successfully confirmed that the proxy listener is active and have configured your browser to work with Burp

Note

If you previously installed a different CA certificate generated by Burp, you should remove it before installing a new one.

  1. Make sure that Burp Suite is running.
  2. Visit http://burpsuite in Chrome.
