Firefox browser launches blank page while running tests via Selenium

Question

I have created a simple test that launches browser and calls a URL. This works fine in IE but when I select Firefox (FF) browser it opens a blank page. See the code snippet below.

The issue is similar to this post that concludes one has to change the settings in about:config's toolkit.telemetry.prompted to 2.

But in my case its already 2, hence I have posted the issue.

Any help would be appreciated.

import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import org.openqa.selenium.server.SeleniumServer;
import org.testng.annotations.AfterSuite;
import org.testng.annotations.BeforeSuite;

import com.thoughtworks.selenium.*;

public class BascOne  extends SeleneseTestBase {
    private SeleniumServer seleniumserver;

    //start the selenium server
    @Before
    public    void startServer()
    {
        try {


        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }


    @Test
    public void launchTest() throws Exception
    {
        seleniumserver = new SeleniumServer();

        seleniumserver.start();


        setUp("http://yahoo.com/", "firefox");
        selenium.windowMaximize();
        selenium.windowFocus();


        System.out.println("IN THE  TEST METHOD");

        selenium.open("http://yahoo.com/");    

        System.out.println("BEFORE WAIT");        

        if(selenium != null){
            System.out.println("Is there any exception");
            try {
                System.out.println("In the try block");

                selenium.close();
                selenium.shutDownSeleniumServer();        


            } catch(Exception exp) {
                System.out.println("Shutdown exception: " + exp.getMessage());
            }

        }

    }


    @After
    public void tearDown()  {
    }    
}

Answer 1

This is because of compatibility issue with your browser and Selenium libs. Selenium libs 2.16 supports Firefox version 3.6 to 11, and for 12 you have to upgrade your Selenium libs to 2.22.

Answer 2

I had a similar issue and found the problem was the combination of firefox version and selenium server version. You could try either downgrading firefox or upgrading selenium to the latest version.

Check out http://seleniumhq.org/about/platforms.html#browsers browsers supported in the latest versions, note that the latest version only supports up to firefox 10 at the moment...
