Follow the steps below to check your browser proxy configuration.
These steps are only necessary if you want to use an 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.
These steps enable you to test web applications that use HTTP. To test HTTPS URLs, you need to install Burp's CA certificate.
