【问题描述】：
我在 Windows 7 上使用 selenium-standalone-server-2.39 作为 RemoteWebDriver[服务器在不同的机器上运行] 和 firefox 26。测试执行工作正常但是当代码尝试 关闭或退出驱动程序/浏览器 在套件拆解期间，它会给出 UnreachableBrowserException。 虽然如果我在本地使用 webdriver [服务器在同一台机器上运行]，它可以完美运行。
我已经尝试过使用 ff 26 的不同版本的 webdriver 2.36、2.37、2.38，但每次都会出现相同的异常。
如果有人帮我解决这个问题，那将非常有帮助。
selenium webdriver 和 firefox 的哪种组合可以完美运行？
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();
}
例外：

浏览器和驱动程序的所有组合都可以正常工作。唯一的问题是如果您使用的是二进制 Chrome 或 IE 驱动程序，并且您的浏览器版本太新，二进制驱动程序无法处理，即使那样，错误也不常见。你一定在做一些不寻常的事情。您应该发布更多详细信息。
