The default browser of PhantomJS is IE, though many browser features do not work there. If you want to open a headless(hidden) Firefox window, you can use the new feature of Firefox 56+.

With this feature you can get a headless driver like this:

System.setProperty("webdriver.gecko.driver", firefoxDriverExePath);
FirefoxOptions options = new FirefoxOptions();
options.addArguments("--headless");
FirefoxDriver driver = new FirefoxDriver(options);

New versions of Chrome also have the headless option.
