Selenium WebDriver - FirefoxOptions

Quiz

FirefoxOptions is a specific class in Selenium Webdriver which helps to handle options which are only applicable to the Firefox driver. It helps to modify the settings and capabilities of the browser while running an automated test on Firefox. The FirefoxOptions class extends another class known as the MutableCapabilities class. The FirefoxOptions class is available in the latest version of Selenium.

Open in Headless Browser Using FirefoxOptions

In this example, we would open and launch an application in the headless mode using the FirefoxOptions class.

package org.example;

import org.openqa.selenium.*;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.firefox.FirefoxOptions;
import java.io.File;
import java.util.List;
import java.util.concurrent.TimeUnit;

public class FirefoxOptnsHeadless {
   public static void main(String[] args) throws InterruptedException {

      // object of FirefoxOptions
      FirefoxOptions opt = new FirefoxOptions();

      // open in headless mode
      opt.addArguments("-headless");

      // Initiate the Webdriver
      WebDriver driver = new FirefoxDriver(opt);

      // adding implicit wait of 15 secs
      driver.manage().timeouts().implicitlyWait(15, TimeUnit.SECONDS);

      // Opening the webpage with headless mode
      driver.get("https://www.tutorialspoint.com/selenium/practice/selenium_automation_practice.php");

      // getting page title
      System.out.println("Getting the page title: " + driver.getTitle());

      // Quitting browser
      driver.quit();
   }
}

It will show the following output −

Getting the page title: Selenium Practice - Student Registration Form

Process finished with exit code 0

In the above example, we observed that the Firefox browser was launched in a headless mode. We had also obtained the browser title with the message in the console - Getting the page title: Selenium Practice Student Registration Form.

SSL Certificates Using FirefoxOptions

SSL certificate errors in the Firefox browser, can be handled with the FirefoxOptions class along with the DesiredCapabilities class.

package org.example;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.firefox.FirefoxOptions;
import org.openqa.selenium.remote.CapabilityType;
import org.openqa.selenium.remote.DesiredCapabilities;
import java.util.concurrent.TimeUnit;

public class SSLErrorFirefox {
   public static void main(String[] args) throws InterruptedException {
   
      // Desired Capabilities class to profile Firefox
      DesiredCapabilities dc = new DesiredCapabilities();
      dc.setCapability(CapabilityType.ACCEPT_INSECURE_CERTS, true);
      
      // Firefox Options class
      FirefoxOptions opt = new FirefoxOptions();
      opt.merge(dc);
      
      // Initiate the Webdriver with options
      WebDriver driver = new FirefoxDriver(opt);
      
      // adding implicit wait of 15 secs
      driver.manage().timeouts().implicitlyWait(15, TimeUnit.SECONDS);
      
      // launch application with SSL error
      driver.get("https://expired.badssl.com");
      
      // get browser title
      System.out.println("Browser title in Firefox: " + driver.getTitle());
      
      // quitting the browser
      driver.quit();
   }
}

It will show the following output −

Browser title in Firefox: Privacy error

In the above example, we had the SSL Certificate error in Firefox and launched the application and then obtained the browser title with the message in the console - Browser title in Firefox: Privacy error.

Firefox Profile Using FirefoxOptions

Let us take an example, where we would launch the Firefox browser with our own Firefox profile.

package org.example;

import org.openqa.selenium.*;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.firefox.FirefoxOptions;
import org.openqa.selenium.firefox.FirefoxProfile;
import org.openqa.selenium.firefox.ProfilesIni;
import java.util.concurrent.TimeUnit;

public class FirefoxOptnsProfile {
   public static void main(String[] args) throws InterruptedException {

      // object of FirefoxOptions
      FirefoxOptions opt = new FirefoxOptions();

      // object of ProfilesIni
      ProfilesIni prof = new ProfilesIni();

      // object of ProfilesIni
      FirefoxProfile p = prof.getProfile("<profileName>");
      opt.setProfile(p);

      // Initiate the Webdriver
      WebDriver driver = new FirefoxDriver(opt);

      // adding implicit wait of 15 secs
      driver.manage().timeouts().implicitlyWait(15, TimeUnit.SECONDS);

      // Opening the webpage
      driver.get("https://www.tutorialspoint.com/selenium/practice/selenium_automation_practice.php");

      // getting page title
      System.out.println("Getting the page title: " + driver.getTitle());

      // Quitting browser
      driver.quit();
   }
}

It will show the following output −

Getting the page title: Selenium Practice - Student Registration Form

In the above example, we observed that the Firefox browser was launched with a created profile. We had also obtained the browser title with the message in the console - Getting the page title: Selenium Practice - Student Registration Form.

Open Maximized Browser Using FirefoxOptions

In this example, we would open and launch an application in the browser maximized size.

package org.example;

import org.openqa.selenium.*;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.firefox.FirefoxOptions
import java.io.File;
import java.util.Collections;
import java.util.concurrent.TimeUnit;

public class FirefoxOptnsMaximized {
   public static void main(String[] args) throws InterruptedException {

      // object of FirefoxOptions
      FirefoxOptions opt = new FirefoxOptions();

      // open browser in maximized mode
      opt.addArguments("--kiosk")

      // Initiate the Webdriver
      WebDriver driver = new FirefoxDriver(opt);

      // adding implicit wait of 15 secs
      driver.manage().timeouts().implicitlyWait(15, TimeUnit.SECONDS);

      // Opening the webpage 
      driver.get("https://www.tutorialspoint.com/selenium/practice/tabs.php");

      // quitting browser
      driver.quit();
   }
}

It will show the following output −

Process finished with exit code 0

In the above example, we observed that the Firefox browser was launched in a maximized browser.

Conclusion

This concludes our comprehensive take on the tutorial on Selenium Webdriver Firefox Options. Weve started with describing a FirefoxOptions class, and walked through examples of how to add profiles to Firefox browser, how to launch the Firefox browser maximized, how to open the Firefox browser in headless mode, and handle SSL certificates errors taking help of FirefoxOptions along with Selenium Webdriver.
