You can handle the Firefox driver automatically using WebDriverManager.

This library downloads the proper binary (geckodriver) for your platform (Mac, Windows, Linux) and then exports the proper value of the required Java environment variable (webdriver.gecko.driver).

Take a look at a complete example as a JUnit test case:

public class FirefoxTest {

  private 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
  }
}

If you are using Maven you have to put at your pom.xml:

    io.github.bonigarcia
    webdrivermanager
    4.2.2

WebDriverManager does magic for you:

1. It checks for the latest version of the WebDriver binary
2. It downloads the WebDriver binary if it's not present on your system
3. It exports the required WebDriver Java environment variables needed by Selenium

So far, WebDriverManager supports Chrome, Opera, Internet Explorer, Microsoft Edge, PhantomJS, and Firefox.
