Since upgrading to the latest version of Selenium the following code seems to be deprecated:
Selenium 3.6.0 & webdriver = new FirefoxDriver(capabilities) - deprecated?
Full code:
System.setProperty("webdriver.gecko.driver", Base_Page.getConstant(Constant.GECKO_DRIVER_DIRECTORY));
DesiredCapabilities capabilities=DesiredCapabilities.firefox();
capabilities.setCapability("marionette", true);
webdriver = new FirefoxDriver(capabilities); //deprecated

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.
