This is because Selenium 3 uses a seperate driver to interact with the Firefox browser.
这是因为 Selenium 3 使用单独的驱动程序与 Firefox 浏览器交互。

Add the path of geckodriver.exewith System.setProperty. Assuming path C:\Selenium\Firefox driver\geckodriver.exe:
添加geckodriver.exewith的路径System.setProperty。假设路径C:\Selenium\Firefox driver\geckodriver.exe：
System.setProperty("webdriver.gecko.driver","C:\Selenium\Firefox driver\geckodriver.exe");
WebDriver driver = new FirefoxDriver();
