这里似乎有什么问题？

调查Selenium ChangeLog I'm afraid selenium-firefox-driver-2.33.0.jar will support at most Firefox 20 so you will need to downgrade your Firefox version. You can download previous Firefox version(s) from Mozilla FTP website

另一种选择是升级到最新版本的 JMeter WebDriver Sampler plugin, you can do it using JMeter Plugins Manager。根据 WebDriver Sampler 版本 1.4.0，您应该得到 selenium-firefox-driver-2.52.0.jar，它应该支持 Firefox 46。
