Selenium 2.48.2 +firefox 42 +浏览器没有被实例化答案

【问题标题】：Selenium 2.48.2 +firefox 42 +browser not getting instantiatedSelenium 2.48.2 +firefox 42 +浏览器没有被实例化
【发布时间】：2016-02-15 20:37:14
【问题描述】：

我已从 2.46.0 升级到 Selenium 2.48.2，并将 firefox 升级到最新版本 42。升级后，浏览器未实例化。

所有项目都在发生这种情况。我也尝试过降级 firefox 和 selenium，但没有帮助。

请推荐！！

以下是错误：

【问题讨论】：

我有相同的设置（windows 7，firefox 42，selenium-server-standalone-2.48.2.jar），firefox.exe 启动但对driver.get(baseURL); 的调用抛出空指针异常:(必须检查兼容性

标签： java firefox selenium

【解决方案1】：

根据我的经验，Selenium Webdriver 不支持最新版本的 Firefox。尝试降级到更少的先前版本。您可以尝试检查 Selenium 的 CHANGELOG，它们指的是一些可能会工作的版本。

然后，如果您想要特定的以前版本的 Firefox，请转到他们的previous versions page。

【讨论】：

我这样做了，但没有帮助。谢谢

【解决方案2】：

尝试使用 selenium 2.48.2 和具有原生事件支持的 firefox 33。但到目前为止，它也可以工作到 Firefox 41。欲了解更多信息，请查看以下链接>>https://raw.githubusercontent.com/SeleniumHQ/selenium/master/dotnet/CHANGELOG

【解决方案3】：

我遇到了几个版本的问题，在 Firefox 升级后它根本无法工作，即使其他版本似乎没有任何问题。

我清除了配置文件，它开始为我工作，然后我将 cookie 数据库复制到新的配置文件中，因为这是一个很难重建的要求。

【解决方案4】：

在这种情况下，您有两种解决方案：

降级您的 firefox 和 selenium 版本（例如，我目前使用 selenium 2.46.0 和 FF 41.0.1），
将 FF 升级到 43.0 版本，可与 selenium 2.48.2 完美配合
