我使用的是selenium 3.4.0、Java1.8和firefox 54.0.1（64位）。当我尝试打开firefox的链接时，出现了一个空指针异常。当我使用selenium/python时，它工作得很好，但是我正在尝试运行这个guru99页面上的代码(https://www.guru99.com/first-webdriver-script.html)。我搜索过是否有其他人有此问题，但找不到任何解决方法。我得到以下输出：

下面的错误消息clears说，您使用的selenium和geckdriver版本不支持当前的firefox，因为它已经升级。

1501246654252   addons.manager  DEBUG   Application has been upgraded

有两种方法可以解决这个问题
升级webdriver和geckdriver
降级firefox

以下是您问题的答案：
错误 UnreachableBrowserException: Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure 都说出来了。
按照guru99.com的说法 webdriver.firefox.marionette 内 System.setProperty . 在 Selenium 3.x 我们会用 webdriver.gecko.driver 相反。
因此，请考虑更改代码行：

System.setProperty("webdriver.firefox.marionette","C:\\geckodriver.exe");

收件人：

System.setProperty("webdriver.gecko.driver","C:\\your_directory\\geckodriver.exe");

如果这能回答你的问题，请告诉我。
