This is an ongoing issue with geckodriver: https://github.com/mozilla/geckodriver/issues/659

If you still want to work with firefox : you can downgrade firefox to v52 and then along with geckodriver v0.15 you'll be able to work fine.

Try this way..Download gecko_driver from this link

Note:- If your dealing with latest gecko driver version(v0.16.0), make sure your firefox browser is updated to latest version(V53).

Update selenium jar files as well as. you can download selenium latest jar files from this link

System.setProperty("webdriver.gecko.driver", "C:\\Drivers\\geckodriver.exe");   // Your gecko_driver path.
WebDriver driver = new FirefoxDriver();
driver.manage().window().maximize();
driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
driver.get("https://www.facebook.com");
driver.findElement(By.name("email")).sendKeys("Username");

To work with Selenium 3.4.0 you need to download gecko driver v0.16.0 or higher from here and save it. Upgrade your Mozila Firefox to 53.x

Next you need to provide the absolute path of the gecko driver in your code. Your code will look like:

    System.setProperty("webdriver.gecko.driver",  "C:\\Utility\\BrowserDrivers\\geckodriver.exe");
    FirefoxDriver driver =  new FirefoxDriver();
    driver.manage().window().maximize();
    driver.get("https://www.facebook.com/");
    driver.findElement(By.name("email")).sendKeys("your_username");

Let me know if this helps you.
