I'm trying the below code. But its still giving dialog box for entering username and password when firefox browser starts. Where am I wrong?
FirefoxProfile profile = new FirefoxProfile();
Proxy firefox_proxy = new Proxy();
firefox_proxy.HttpProxy = proxy;
firefox_proxy.SslProxy = proxy;
profile.SetProxyPreferences(firefox_proxy);
Firefoxdriver driver = new FirefoxDriver(new FirefoxBinary(), profile, TimeSpan.FromMinutes(3));
driver.Navigate().GoToUrl("http://" + proxy_username + ":" + proxy_password + "@www.xyz.com/");
