Answer 1

From https://raw.githubusercontent.com/SeleniumHQ/selenium/master/rb/CHANGES

3.4.1 (2017-06-13)
==================
Firefox:
  * Added new Firefox::Options class that should be used to customize browser
    behavior (command line arguments, profile, preferences, Firefox binary, etc.).
    The instance of options class can be passed to driver initialization using
    :options key. Old way of passing these customization directly to driver
    initialization is deprecated.

From the 3.4.1 version the FirefoxOptions should be used.

Answer 2

Changed the following code 'FirefoxDriver(capabilities) to firefoxOptions which uses .setCapcability()

FirefoxOptions firefoxOptions = new FirefoxOptions();
    firefoxOptions.setCapability("marionette", true);
    webdriver = new FirefoxDriver(firefoxOptions);

Answer 3

Try following:

    FirefoxOptions firefoxOptions = new FirefoxOptions();
    firefoxOptions.setCapability("marionette", true);
    WebDriver driver = new FirefoxDriver(firefoxOptions);

Answer 4

You can try this line;

FirefoxOptions ffOpt = new FirefoxOptions();
ffOpt.setCapabilities("marionette", true);
WebDriver driver = new FirefoxDriver(ffOpt);
