我已从2.46.0升级到Selenium 2.48.2，并已将firefox升级到最新版本42.升级后，浏览器未实例化。
所有项目都会发生这种情况。我也尝试降级firefox和selenium，但它没有帮助。
请建议!!
以下是错误：

根据我的经验，Selenium Webdriver不支持最新版本的Firefox。尝试降级到较少的先前版本。您可以尝试查看Selenium的CHANGELOG，在那里他们会参考一些可能会有效的版本。
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。

尝试使用具有本机事件支持的firefox 33的selenium 2.48.2。但截至目前，它将一直运行到firefox 41。 有关详细信息，请查看以下链接＆gt;＆gt; https://raw.githubusercontent.com/SeleniumHQ/selenium/master/dotnet/CHANGELOG
