Answer 1

代码加上这两行
System.setProperty("webdriver.firefox.bin", "C:/Program Files/Mozilla Firefox/firefox.exe"); //你的火狐浏览器的安装路径
System.setProperty("webdriver.gecko.driver","C:\\Program Files\\Mozilla Firefox\\geckodriver.exe"); //geckodriver.exe的路径
然后，下载不同版本的geckodriver.exe放到相应的目录试下，不是越新版本的越好，总之各个版本的都试下。我之前 就是因为这个geckodriver.exe的版本原因，遇到的问题和你一模一样。也是打开了浏览器然后网页空白。

Answer 2

有可能是以下原因导致的
1 你的firefox的版本是不是48+？
2 你的操作系统是32位还是64位,你用的geckodriver 是32位还是64？
