可能有两个问题
WebDriver driver = new FirefoxDriver（new FirefoxBinary（new file（“path / to / your / firefox.exe”）），profile）;
要解决此问题，请访问selenium网站，并确保您的浏览器兼容版本 Selenium Change Log
答案 1 :(得分：0)
这是因为firefox的最新浏览器中出现了新问题。
更新您的硒罐。新版本的firefox（或不同的浏览器）不支持旧版的selenium。
下载Selenium Server（以前的Selenium RC Server）Selenium Client＆amp; WebDriver语言绑定
用您正在使用的旧罐子替换它们。同时更新您的mozilla，以便获得更新的结果
来源： - http://docs.seleniumhq.org/download/
要解决此问题，您还需要将setPreference设置为xpinstall.signatures.required", false到firefox配置文件，然后将其传递给驱动程序对象
firefoxProfile.setPreference("xpinstall.signatures.required", false);
下面的代码对我来说很好。
static WebDriver driver=null;
public static void main(String[] args) {
final FirefoxProfile firefoxProfile = new FirefoxProfile();
firefoxProfile.setPreference("xpinstall.signatures.required", false);
driver = new FirefoxDriver(firefoxProfile);
driver.get("https://www.google.de/");
希望它会对你有所帮助:)。
