Unable to launch Firefox browser from Selenium Webdriver version 3.4.0

I am facing an issue wherein I am unable to launch firefox from Selenium Webdriver version 3.4.0 from my Windows operating system (Windows 7) which is 64 bit. Currently, firefox version 52.0.2 is installed on my machine. I have also added selenium jar files to the library, still it is showing error.

My code:

package sanity;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;

public class Login
{
        public static void main(String[] args)    
        {
            WebDriver driver=new FirefoxDriver();    
            driver.close(); 
        }
}

Error:

Exception in thread "main" java.lang.IllegalStateException: The path to the driver executable must be set by the webdriver.gecko.driver system property; for more information, see https://github.com/mozilla/geckodriver. The latest version can be downloaded from https://github.com/mozilla/geckodriver/releases

    at org.openqa.selenium.firefox.FirefoxDriver.<init>(FirefoxDriver.java:104)
    at sanity.Login.main(Login.java:18)

After this, I downloaded GeckoDriverService form SeleniumHQ.org and ran below code, now after running below updated code with the Geckodriver path, firefox browser is getting launched but not closing automatically. Also I am getting some message in console.

Code: 

package sanity;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;

public class Login 
{

        public static void main(String[] args) 
        {

          String Firefoxdriverpath="C://Users//Ashish//Downloads//geckodriver-v0.16.0-win64//geckodriver.exe";

            System.setProperty("webdriver.gecko.driver", Firefoxdriverpath);

            WebDriver driver=new FirefoxDriver();

            driver.close(); 
        }

}

Console:

Please, try it again using "driver.quit" instead of "driver.close".

About the "Javascript error (AddonManager)" I'm still trying to figure out how to fix it too, if someone know a way please share with us :)

Can you please try the below code,

String Firefoxdriverpath="C://Users//Ashish//Downloads//geckodriver-v0.16.0-win64//geckodriver.exe";
System.setProperty("webdriver.gecko.driver", Firefoxdriverpath);
DesiredCapabilities capabilities = DesiredCapabilities.firefox();
capabilities.setCapability("marionette", true);
WebDriver driver = new FirefoxDriver(capabilities);  
driver.close();

Please let me know if this is working.

I had the similar issue but finally got it solved by this small code below changed for selenium 3.4 capability-

DesiredCapabilities capabilities = DesiredCapabilities.firefox();

capabilities.setCapability("marionette", false); // true gives that Javascript error (AddonManager is not initialized)

What is your Firefox version??

sometimes the problem is the incompatibility between the installed FireFox version and the geckodriver version

About the "Javascript error (AddonManager)"... I almost went nuts today trying to fix this, since all the components were installed gradually within the last week.In the end I solved it. Here's the solution and the explanation: geckodriver v.0.16.0 "is only compatible with Selenium 3.4 and greater" (as it says on their page). A week ago selenium 3.3.1 was the last version. As of April 21, selenium3.4.0 was released. I had to recreate the project from scratch, re-adding the Selenium jars. For some reason simply replacing them on the old project, didn't do the trick.

I don't see any significant error in your code as such. But you need to follow certain guidelines as follows:

While declaring String Firefoxdriverpath either you need to use single front slashes i.e "/"

e.g. String Firefoxdriverpath="C:/Utility/BrowserDrivers/geckodriver.exe";

OR you need to escape the back slashes i.e "\\"

e.g. String Firefoxdriverpath="C:\\Utility\\BrowserDrivers\\geckodriver.exe";

Let me know if this works for you.

I had the same issue. What helps is usage of driver.quit(); instead of driver.close();

Got this error when using Firefox version: 45.9.0; Selenium 3.4.0 and Gecko driver: 16.1.

Solution: Downgrade to gecko 16.0 and use: System.setProperty("webdriver.firefox.marionette", "Path");

Hope this helps.
