How to use firefox webdriver geckodriver in selenium

Question

I am unable to use geckodriver with selenium in Java. I am using firefox v42 and geckodriver v23. 

The code I am using is as follows:-

System.setProperty("webdriver.gecko.driver","C:\\Users\\Downloads\\Firefox1\\geckodriver.exe");
WebDriver driver = new FirefoxDriver();
driver.get("https://www.google.com");
driver.close();

The problem that I am facing is that geckodriver is opening but after opening I am getting an error like this:-

Answer 1

Firefox v47+ with selenium 2.53, you need marionette driver and you export its absolute path to variable webdrive.gecko,driver as system property.

Firefox v47+ will support geckodriver only.

Please upgrade to selenium java binding 3.4+

If you use old version of Morzilla Firefox and newer version of Selenium you will be facing error like :

Exception in thread "main" java.lang.IlleagalStateException

If you use new version of Morzilla Firefox and older version of Selenium you will be facing error like:

org.openqa.selenium.SessionNotCreatedException: Unable to create new remote session.

Hence as a suggestion use:

Firefox V64 as of Jan 2019

Selenium 3.4+
