问题：
Selenium启动错误：org。openqa。硒。火狐。NotConnectedException:无法连接到端口7055上的主机127.0.0.1
戚明朗
当我试图通过java运行一个非常简单的selenium脚本时，我遇到了这个错误。尝试创建新的FireFoxWebDriver（）
我在网上看到过类似的错误，但它们都很老了，似乎都没有好的解决方案。我正在使用selenium java和selenium firefox驱动程序2.51.0版。我的firefox版本是43.0.2，selenium网站说他们支持最新版本的firefox，所以我认为这不是问题所在。
任何帮助都非常感谢，谢谢！

如果您使用的是selenium版本3：
System.setProperty("webdriver.gecko.driver","C:\\Users\\vipin\\Downloads\\Compressed\\geckodriver.exe");
如果上述属性不起作用或无法在浏览器中打开应用程序，请尝试以下操作：
System.setProperty("webdriver.firefox.marionette","C:\\Users\\vipin\\Downloads\\Compressed\\geckodriver.exe");

检查您的传递依赖关系，并确保您确实使用了您认为是的Selenium版本（2.51.0）
回顾FirefoxDriver的历史，它对连接的调用。start（）已经很长时间没有出现在第247行了（比如，2014年）。现在是271。
我怀疑你正在使用2.40.0，因为另一个WebDriver组件覆盖了你的首选版本。在这种情况下，你可能会遇到和其他人过去一样的问题。
请参阅：为什么我收到selenium错误“firefox bin预期退出”，并且无法连接到端口7055等上的主机127.0.0.1。
更新：事实上，如果你读到下面的2/3，就会得到确认：
Build info: version: '2.42.2', revision: '6a6995d31c7c56c340d6f45a76976d43506cd6cc'
大家一致认为问题在于版本不兼容，因此应该升级到最新的WebDriver版本。
