WebDriver：org.openqa.selenium.firefox.NotConnectedException: Unable to connect to host 127.0.0.1 on port 7055 after 45000 ms

今天尝试最新的webDriver与fireFox搭配：
  运行代码时出现如下的问题，但是浏览器却可以打开：

org.openqa.selenium.firefox.NotConnectedException 一般这个错误，表示webDriver与fireFox不兼容，webDriver的版本太低，但是我的WebDriver的相关jar的版本是最高的，2.25.0 。

最后发现原来是在eclipse中的webDriver没有更换成最新的jar。

目前经过测试：

webDriver2.25.0 +fireFox36.0

webDriver 2.24+fireFox34.0

可以兼容。
