How to use toString method of org.openqa.selenium.events.EventName class

Unless you are creating a profile that explicitly installs firefox extensions/plugins Selenium Webdriver will create a blank profile and use that.

Can you show us what code you are using to call the FF driver?

 if (attribute.equals(null)) {
    return true;
  }`

If attribute is null then .equals call will lead to NPE. Try with attribute == null.

Use Actions class to perform mouse, keyboard actions on WebElements using WebDriver.

Actions action = new Actions(driver);
WebElement element=driver.findElement(By.linkText("TEST"));

//Double click
action.doubleClick(element).perform();

//Mouse over
action.moveToElement(element).perform();

//Right Click
action.contextClick(element).perform();

different dialogs handling using selenium webDriver:

import org.openqa.selenium.Alert;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;

public class JavaScriptAlertTest {

public static void main(String[] args) {

    WebDriver myTestDriver = new FirefoxDriver();
    myTestDriver.get("...blablabla....");

    myTestDriver.manage().window().maximize();

    myTestDriver.findElement(By.xpath("//input[@value = 'alert']")).click();

    Alert javascriptAlert = myTestDriver.switchTo().alert();
    System.out.println(javascriptAlert.getText()); // Get text on alert box
    javascriptAlert.accept();

    System.out.println("*************prompt******************************************");

    myTestDriver.findElement(By.xpath("//input[@value = 'prompt']")).click();

    Alert javascriptprompt = myTestDriver.switchTo().alert();
    javascriptprompt.sendKeys("This is Selenium Training");

    System.out.println(javascriptprompt.getText()); // Get text on alert box

    javascriptprompt.accept();
    javascriptprompt = myTestDriver.switchTo().alert();

    System.out.println(javascriptprompt.getText()); // Get text on alert box
    javascriptprompt.accept();

    myTestDriver.findElement(By.xpath("//input[@value = 'prompt']")).click();

    javascriptprompt = myTestDriver.switchTo().alert();

    System.out.println(javascriptprompt.getText()); // Get text on alert box

    javascriptprompt.dismiss();
    javascriptprompt = myTestDriver.switchTo().alert();

    System.out.println(javascriptprompt.getText()); // Get text on alert box
    javascriptprompt.accept();

    System.out.println("***********************************confirm dialog box****************************");
    myTestDriver.findElement(By.xpath("//input[@value = 'confirm']")).click();

    Alert javascriptconfirm = myTestDriver.switchTo().alert();
    javascriptconfirm.accept();

    javascriptconfirm = myTestDriver.switchTo().alert();
    System.out.println(javascriptconfirm.getText()); // Get text on alert box
    javascriptconfirm.accept();

    myTestDriver.findElement(By.xpath("//input[@value = 'confirm']")).click();
    javascriptconfirm = myTestDriver.switchTo().alert();

    javascriptconfirm.dismiss();
    javascriptconfirm = myTestDriver.switchTo().alert();
    System.out.println(javascriptconfirm.getText()); // Get text on alert box
    javascriptconfirm.accept();

}
}

Hope it helps you:)

Unfortunately Selenium WebDriver 2.53.0 is not compatible with Firefox 47.0. The WebDriver component which handles Firefox browsers (FirefoxDriver) will be discontinued. As of version 3.0, Selenium WebDriver will need the geckodriver binary to manage Firefox browsers. More info here and here.

Therefore, in order to use Firefox 47.0 as browser with Selenium WebDriver 2.53.0, you need to download the Firefox driver (which is a binary file called geckodriver as of version 0.8.0, and formerly wires) and export its absolute path to the variable webdriver.gecko.driver as a system property in your Java code:

System.setProperty("webdriver.gecko.driver", "/path/to/geckodriver");

Luckily, the library WebDriverManager can do this work for you, i.e. download the proper Marionette binary for your machine (Linux, Mac, or Windows) and export the value of the proper system property. To use this library, you need to include this dependency into your project:

<dependency>
    <groupId>io.github.bonigarcia</groupId>
    <artifactId>webdrivermanager</artifactId>
    <version>5.1.0</version>
</dependency>

... and then execute this line in your program before using WebDriver:

WebDriverManager.firefoxdriver().setup();

A complete running example of a JUnit 4 test case using WebDriver could be as follows:

public class FirefoxTest {

    protected WebDriver driver;

    @BeforeClass
    public static void setupClass() {
        WebDriverManager.firefoxdriver().setup();
    }

    @Before
    public void setupTest() {
        driver = new FirefoxDriver();
    }

    @After
    public void teardown() {
        if (driver != null) {
            driver.quit();
        }
    }

    @Test
    public void test() {
        // Your test code here
    }
}

Take into account that Marionette will be the only option for future (for WebDriver 3+ and Firefox 48+), but currently (version 0.9.0 at writing time) is not very stable. Take a look to the Marionette roadmap for further details.

UPDATE

Selenium WebDriver 2.53.1 has been released on 30th June 2016. FirefoxDriver is working again with Firefox 47.0.1 as browser.

If you are on Java-8 you can run a parallel for loop using aparallelStream

 IntStream.range(0,20).parallel().forEach(i->{
         ... do something here
 });

The submit() function is there to make life easier. You can use it on any element inside of form tags to submit that form.

You can also search for the submit button and use click().

So the only difference is click() has to be done on the submit button and submit() can be done on any form element.

It's up to you.

Create cookies using the Java API as follows:

Cookie ck = new Cookie("name", "value");
driver.manage().addCookie(ck);

Create cookies using the Python API as follows:

driver.add_cookie({'name': 'foo', 'value': 'bar'})

If you want the HTML of the element itself, you can use

webElement.getAttribute("outerHTML");

It will return the HTML of the element itself plus all the children elements. I'm not sure if that's exactly what you want. I don't think there is a way to just get the HTML of the selected element only.
