C# Selenium/ChromeDriver Add User Profile Preference

Question

I need to allow all cookies when running tests with selenium + chrome driver.

I am trying to add this as a profile preference using ChromeOptions.AddUserProfilePreference

I'm not 100% sure what the preference name should be to allow all cookies. I have referenced this doc https://src.chromium.org/viewvc/chrome/trunk/src/chrome/common/pref_names.cc?view=markup

and have tried the following in my setup but its not having the desired effect.

options.AddUserProfilePreference("profile.block_third_party_cookies", false);

options.AddUserProfilePreference("security.cookie_behavior", 0);```

Here is my setup code

                        new DriverManager().SetUpDriver(new ChromeConfig());
                        var options = new OpenQA.Selenium.Chrome.ChromeOptions { };
                        options.AddArgument("–no-sandbox");
                        options.AddArguments("-disable-gpu");
                        options.AddArguments("-disable-dev-shm-usage");
                        options.AddArgument("-incognito");
                        options.AddArgument("-start-maximized");
                        options.AddUserProfilePreference("security.cookie_behavior", 0);
                        CurrentWebDriver = new ChromeDriver(options);

I ran into the same issue. I found that using the following helped me:

options.AddUserProfilePreference("profile.cookie_controls_mode", 0);

The advice that helped me find this, was to check the Chrome preferences file (in my case C:\Users\<user>\AppData\Local\Google\Chrome\User Data\Default\Preferences). I saved a copy with cookies blocked, then changed the setting to allow all cookies and compared the two versions, and that highlighted the affected control for me.

Great solution, working for me too, thanks – G. Victor Dec 10 '20 at 08:43 — G. Victor, Dec 10 '20 at 08:43

Looks like in Chrome v86 third-party cookies disabled by default: Chromium SameSite Updates.

I found a workaround to enable third-party cookies on the browser new tab start page (I'm using inputsimulator library to open a new tab because other methods do not open the appropriate page).

Here is C# code for IWebDriver extension:

using WindowsInput;
using WindowsInput.Native;

public static void EnableThirdPartyCookies(this IWebDriver driver)
{
    var windowHandles = driver.WindowHandles;

    // Activate Browser window
    driver.SwitchTo().Window(driver.WindowHandles.Last());
    
    // Open New Tab Ctrl + T    
    new InputSimulator().Keyboard.ModifiedKeyStroke(VirtualKeyCode.CONTROL, VirtualKeyCode.VK_T);

    // Wait for open new tab
    const int retries = 100;
    for (var i = 0; i < retries; i++) 
    {
        Thread.Sleep(100);
        if (driver.WindowHandles.Count > windowHandles.Count)
            break;
    }

    // Enable Third Party Cookies
    if (driver.WindowHandles.Count > windowHandles.Count)
    {
        driver.Close();
        driver.SwitchTo().Window(driver.WindowHandles.Last());
        var selectedCookieControlsToggle = driver.FindElements(By.Id("cookie-controls-toggle"))
            .FirstOrDefault(x => x.GetAttribute("checked") != null);
        selectedCookieControlsToggle?.Click();
    }
}

Using:

var chromeService = ChromeDriverService.CreateDefaultService();
var options = new ChromeOptions { };
options.AddArgument("–no-sandbox");
options.AddArgument("-incognito");
options.AddArgument("-start-maximized");
var driver = new ChromeDriver(chromeService, options);
driver.EnableThirdPartyCookies();

Here is Java code:

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.chrome.ChromeOptions;
import org.openqa.selenium.remote.RemoteWebDriver;
import java.awt.*;
import java.awt.event.KeyEvent;
import java.util.ArrayList;
import java.util.List;
import java.util.Optional;

public void enableThirdPartyCookies(WebDriver driver) throws Exception {
    ArrayList<String> windowHandles = new ArrayList<String> (driver.getWindowHandles());

    // Activate Browser window
    driver.switchTo().window(driver.getWindowHandle());

    // Open New Tab Ctrl + T
    Robot robot = new Robot();
    robot.keyPress(KeyEvent.VK_CONTROL);
    robot.keyPress(KeyEvent.VK_T);
    robot.keyRelease(KeyEvent.VK_T);
    robot.keyRelease(KeyEvent.VK_CONTROL);

    // Wait for open new tab
    int retries = 100;
    for (int i = 0; i < retries; i++)
    {
        Thread.sleep(100);
        if (driver.getWindowHandles().size() > windowHandles.size())
            break;
    }

    // Enable Third Party Cookies
    if (driver.getWindowHandles().size() > windowHandles.size())
    {
        driver.close();
        windowHandles = new ArrayList<String> (driver.getWindowHandles());
        driver.switchTo().window(windowHandles.get(windowHandles.size() - 1));
        List list = driver.findElements(By.id("cookie-controls-toggle"));
        Optional<WebElement> selectedCookieControlsToggle = driver.findElements(By.id("cookie-controls-toggle")).stream()
                .filter(x -> x.getAttribute("checked") != null).findFirst();
        Optional.ofNullable(selectedCookieControlsToggle).get().get().click();
    }
}

Using:

ChromeOptions options = new ChromeOptions();
options.addArguments("–no-sandbox");
options.addArguments("incognito");
options.addArguments("start-maximized");
WebDriver driver = new ChromeDriver(options);
enableThirdPartyCookies(driver);
