C# Selenium Firefox Set socks proxy with Auth

Question

In C# I'm trying to set socks proxy with authentification in firefox.

This doesn't work

    Proxy proxy = new Proxy();
    proxy.SocksProxy = sProxyIP + ":" + sProxyPort;
    proxy.SocksUserName = sProxyUser;
    proxy.SocksPassword = sProxyPass;
    options.Proxy = proxy;
    _driver = new FirefoxDriver(service, options);

This doesn't work too

   profile.SetPreference("network.proxy.socks", sProxyUser + ":" + sProxyPass + "@" + sProxyIP + ":" + sProxyPort);
   profile.SetPreference("network.proxy.socks_port", sProxyPort);

How can I solve this?

Answer 1

After a lot of researching, here is the solution I decided to go with.

It's a dirty hack, but it works.

I used AutoitX in order to automate the proxy auth window but had to use System.Windows.Automation in order to get the right auth window since my app will be multithreaded.

sProxyIP = "154.5.5.5";
sProxyUser = "user here";
sProxyPass = "pass here";
sProxyPort = 4444;

//Set proxy
profile.SetPreference("network.proxy.socks", sProxyIP);
profile.SetPreference("network.proxy.socks_port", sProxyPort);


//deal with proxy auth
_driver.Manage().Timeouts().PageLoad = TimeSpan.FromMilliseconds(0);
WebsiteOpen(@"https://somewebsite.com/");
AuthInProxyWindow(sProxyUser, sProxyPass);
_driver.Manage().Timeouts().PageLoad = TimeSpan.FromSeconds(60);



void ProxyAuthWindow(string login, string pass)
{
    try
    {   
        //wait for the auth window
        var sHwnd = AutoItX.WinWait("Authentication Required", "", 2);
        AutoItX.WinSetOnTop("Authentication Required", "", 1);

        //we are using Windows UIA so we make sure we got the right auth
         //dialog(since there will be multiple threads we can easily hit the wrong one)
        var proxyWindow = AutomationElement.RootElement.FindFirst(TreeScope.Subtree,
            new PropertyCondition(AutomationElement.ClassNameProperty, "MozillaDialogClass"));
        string hwnd = "[handle:" + proxyWindow.Current.NativeWindowHandle.ToString("X") + "]";
        AutoItX.ControlSend(hwnd, "", "", login, 1);
        AutoItX.ControlSend(hwnd, "", "", "{TAB}", 0);
        AutoItX.ControlSend(hwnd, "", "", pass, 1);
        AutoItX.ControlSend(hwnd, "", "", "{ENTER}", 0);
    }
    catch
    {

    }
