Answer 1

我遇到了这个问题，终于找到了答案。我一直在使用Marionette驱动程序，该驱动程序不再适用于FF版本53和Selenium
3.5或更高版本。该GeckoDriver文档显示系统属性应该如何引用。

我从以下位置更改了代码：

System.setProperty("webdriver.firefox.marionette", System.getProperty("user.dir") + "path");

至：

System.setProperty("webdriver.gecko.driver", System.getProperty("user.dir") + "path");

现在我的本地Firefox运行正常。

希望这对其他人有帮助。
