推荐答案

要在 Mozila Firefox 52.0.2 中使用 Selenium 3.x，您需要:

To work with Selenium 3.x with Mozila Firefox 52.0.2 you need to:

1. 下载最新的 Gecko 驱动程序并将其保存在C:your_folder"中.
2. 将提及 Gecko 驱动程序的 System 属性及其在系统上的绝对路径设置为:

1. Download the latest gecko driver and save it in "C:your_folder".
2. Set the System property mentioning the gecko driver along with its absolute path on your system as:

System.setProperty("webdriver.gecko.driver", "C:\your_folder\geckodriver.exe");

1. 接下来将 Webdriver 初始化为:

WebDriver driver = new FirefoxDriver();

1. 最大化浏览器:

driver.manage().window().maximize();

1. 打开一个网址:

driver.get("http:\gmail.com");

如果这对您有帮助，请告诉我.
