    Also, look at your imports; they are not resolving. Do you have the proper references in your project? – Brian Feb 14 '19 at 1:34
  • sorry...updated – Albin K S Feb 14 '19 at 1:34

For using FirefoxDriver, you now have to use Geckodriver's

public static void main(String[] args) {
// declaration and instantiation of objects/variables
WebDriver driver = new FirefoxDriver();

  • Can you please share the full code. Also like Brian mentioned you have code import resolve issues. Is it resolved now? – Sandeep Chandra Sekhar Feb 14 '19 at 2:37
  • No.when I try to resolve the errors with imports, it shows like " Package org.openqa.selenium.firefox is accessible from more than one moduleclient.cmbined,okio in the popup when mouse hovering above the import statements – Albin K S Feb 14 '19 at 2:41
  • Can you check this link, exact same issue you are mentioning. link – Sandeep Chandra Sekhar Feb 14 '19 at 3:36

There is a issue in your package, I think you missed one of them. I suggest you to use the pom so that it install all of thel automatically. By the way, the webdriver for Firefoix is geckodriver, not marionnette.
