WebDriver window resize | Chrome Driver 2.28 | Chrome 57

I have used set position to change the browser window size in my webdriver automation. When I run the code with Chrome driver 2.28, it throws below exception

**Exception starting line:**

driver.manage().window().setPosition(new Point(pos_x, pos_y));


**Trace:**

**Exception in thread "main" org.openqa.selenium.WebDriverException: unknown error: cannot get automation extension**

The actual use case is to open multiple Chrome windows and make all the windows to be in focus. Now, I'm not able to resize the window.

Final ChromeOptions options = new ChromeOptions(); final String adminToolURL = "http://www.google.com"; options.addArguments("--disable-extensions");

    final WebDriver driver = new ChromeDriver(options);
    driver.manage().window().setSize(new Dimension(500, 600));

    driver.get(adminToolURL);
    driver.getWindowHandles();
    final String adminToolHandle = driver.getWindowHandle();
    int x = 0, y = 30;
    String window = "win";
    for (int i = 1; i <= 3; i++) {
        window = window + String.valueOf(i);
        System.out.println(x);
        System.out.println(y);
        ((JavascriptExecutor) driver)
        .executeScript("window.open('https://www.google.com','"
            + window + "',height=" + x + ",width=" + y + ");");
        final String handle = driver.getWindowHandle();

        driver.switchTo().window(handle.toString());
        // driver.manage().window().setPosition(new Point(pos_x, pos_y));
        pos_x = pos_x + 180;
        if ((i % 7) == 0) {
            pos_y = pos_y + 160;
            pos_x = 0;
        }
        x += 30;
        y += 40;
        Thread.sleep(2000);
        final Set<String> customerWindow = driver.getWindowHandles();
        customerWindow.removeAll(customerWindow);
        driver.switchTo().window(adminToolHandle);
    }
    Thread.sleep(600000);
    driver.quit();
}

I also encountered this problem.

The solution turned out to be very simple - you need to start ChromeDriver with options.

var options = new ChromeOptions();
options.AddArgument("start-maximized");
_driver = new ChromeDriver(options);

The code is on C#. On jave it must be almost the same.

So this is a workaround how you can maximize the browser without getting the error.
