Selenium之firefox浏览器的启动问题及解决

启动firefox报错如下：

rg.openqa.selenium.firefox.NotConnectedException: Unable to connect to host 127.0.0.1 on port 7055 after 45000 ms. Firefox console output:
ailure code: 0x8000ffff (NS_ERROR_UNEXPECTED) [nsINavBookmarksService.removeFolderChildren]

此时的selenium版本为2.44版本，firefox为39。

配置selenium版本为2.52版本即可

参考博客下面博客得知版本对应关系：https://blog.csdn.net/fetch001/article/details/64437979
