Selenium RemoteWebDriver 2.39 with firefox 26 - selenium-webdriver

Question

I'm using selenium-standalone-server-2.39 as RemoteWebDriver[server is running on different machine] with firefox 26 on windows 7.test execution is working fine but when code try to close or quit the driver/browser during suite teardown then it gives UnreachableBrowserException. although If I use webdriver locally[server is running on same machine] it works perfectly.
I have already tried with different version of webdriver 2.36,2.37,2.38 with ff 26 but same exception comes every time.
If someone help me to resolve this problem it will be very helpful.
what combination of selenium webdriver and firefox which works perfectly?
EDIT: This simple piece of code i'm trying to run-
public static void main(String s[]) throws Exception {
URL url = new URL( "http", ip, 4444, "/wd/hub" );
FirefoxProfile pf = new FirefoxProfile(new File("D:\\ffprofile"));
DesiredCapabilities capabilities =DesiredCapabilities.firefox();
capabilities.setCapability(FirefoxDriver.PROFILE, pf);
System.out.println("1");
capabilities.setJavascriptEnabled(true);
System.out.println("2");
WebDriver driver = new RemoteWebDriver(url,capabilities);
System.out.println("4");
driver.get("http://www.google.com");
driver.close();
}
Exception:

Answer 1

Try commenting out this line in your code:
capabilities.setCapability(FirefoxDriver.PROFILE, pf);
Instead of specifying the profile you want to use on your grid, just configure the profile in the grid configuration explicitly, or don't specify profile at all so that Firefox just uses a default profile.
If you look at the release notes for Selenium 2.41.0 ( https://selenium.googlecode.com/git/java/CHANGELOG ) you will notice that Firefox 26 is no longer supported. It was supported in 2.39 but you can use the release notes to make sure you are using the right version. In fact, Selenium 2.44.0 only supports Firefox 24, 31, 32 and 33.

Answer 2

I would try downgrading your version of Firefox
