我使用selenium webdriver创建了一个测试框架，我在 Firefox 44.0.2 中运行相同的版本，2天后它运行正常。
但是现在它打开了firefox浏览器但是没有导航到.get方法中提到的url，下面是我的url导航代码和我得到的异常： -
WebDriver driver=new FirefoxDriver();
driver.get("http://seleniumpractise.blogspot.in/2016/08/how-to-use-explicit-wait-in-selenium.html");
例外： -
org.openqa.selenium.firefox.NotConnectedException: Unable to connect to host 127.0.0.1 on port 7056 after 45000 ms. Firefox console output:

大部分时间都是因为浏览器版本只是升级您的版本并再次运行您的代码
