I have written the code below to open firefox in responsive mode . . The firefox opens in mobile mode but with default size and not the size mentioned in code.

Please check and let me know the issue

public class FirefoxResponsiveMode {

    public static void pressShortcut(WebDriver driver) throws AWTException {
    Robot robot = new Robot();
    robot.keyPress(KeyEvent.VK_SHIFT);
    robot.keyPress(KeyEvent.VK_CONTROL);
    robot.keyPress(KeyEvent.VK_M);
    robot.keyRelease(KeyEvent.VK_SHIFT);
    robot.keyRelease(KeyEvent.VK_CONTROL);
    robot.keyRelease(KeyEvent.VK_M);
    //WebElement e= driver.findElement(By.xpath("html/body"));
    //e.sendKeys(Keys.chord(Keys.CONTROL,Keys.SHIFT));
       // Actions actions = new Actions(driver);
       // actions.keyDown(Keys.CONTROL).keyDown(Keys.SHIFT).sendKeys("m").keyUp(Keys.SHIFT).keyUp(Keys.CONTROL).perform();
    }

    public static void setViewSize(FirefoxProfile profile, String viewDeviceName, Integer width, Integer height) throws InterruptedException {
    Thread.sleep(3000);
      //  String responsiveMode = "[{"width": " + width + ", "name": "" + viewDeviceName + "", "key": "" + width + "x" + height + "", "height": "
         //       + height + "}]";
    String responsiveMode =
                "[{"width": " + width + ", "name": "" + viewDeviceName + "", "key": "" + width + "x" + height + "", "height": "
    + height + "}]";
   

        profile.setPreference("devtools.responsiveUI.presets", responsiveMode);
        Thread.sleep(3000);
    }
}

package test;

import java.awt.AWTException;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.firefox.FirefoxProfile;
import org.openqa.selenium.remote.DesiredCapabilities;

public class MT {

public static void main(String[] args) throws InterruptedException, AWTException {
	System.setProperty("webdriver.gecko.driver", "C:\\Users\\pawan\\Desktop\\geckodriver.exe");
	FirefoxProfile profile = new FirefoxProfile();
	FirefoxResponsiveMode.setViewSize(profile, "Phones", 60, 600);
	DesiredCapabilities cap = DesiredCapabilities.firefox();
	cap.setCapability(FirefoxDriver.PROFILE, profile);
	WebDriver DRIVER = new FirefoxDriver(cap);
	//DRIVER.manage().window().maximize();
	DRIVER.navigate().to("http://rediff.com");
	FirefoxResponsiveMode.pressShortcut(DRIVER);
	//FirefoxResponsiveMode.setViewSize(profile, "mobile", 260, 600);

Without knowing what FirefoxResponseMode is, I can’t tell what’s wrong. There is not enough information in this bug that it is actionable.

You are trying to use features which are only available in chrome scope of Firefox. While staying in content (which is the default) you won't be able to open the responsive design mode of Firefox. So switch the context to chrome first, and then try again. Whereby you will have to check if your Selenium binding is supporting that already or not. For the Python binding it would be driver.set_context("chrome").

I'm keeping this issue closed given the above clarification.
