我正在使用selenium-standalone-server-2.39作为RemoteWebDriver [服务器在不同的机器上运行]在Windows 7上运行firefox 26.测试执行正常但是当代码尝试关闭或退出驱动程序/套件拆解时，它会提供 UnreachableBrowserException。虽然如果我在本地使用webdriver [服务器在同一台机器上运行]，它可以很好地工作。
我已经尝试使用不同版本的webdriver 2.36,2.37,2.38和ff 26 ，但每次都会出现相同的异常。
如果有人帮我解决了这个问题，那将会非常有帮助。
selenium webdriver和firefox的组合完美无缺？
编辑：我正在尝试运行这段简单的代码 - 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();
}

尝试在代码中注释掉这一行：
capabilities.setCapability(FirefoxDriver.PROFILE, pf);
不要指定要在网格上使用的配置文件，只需显式配置网格配置中的配置文件，或者根本不指定配置文件，以便Firefox只使用默认配置文件。
如果您查看Selenium 2.41.0（https://selenium.googlecode.com/git/java/CHANGELOG）的发行说明，您会发现Firefox 26不再受支持。它在2.39中得到支持，但您可以使用发行说明来确保使用正确的版本。实际上，Selenium 2.44.0仅支持Firefox 24,31,32和33。
