    You need to configure your Selenium/ChromeDriver instance to proxy its traffic to Fiddler, which runs at

    suggests you use:

     DesiredCapabilities capabilities =;
    .setCapability("chrome.switches", Arrays.asList("--proxy-server="));

     WebDriver driver = new ChromeDriver(capabilities);
