我使用Selenium 2.47来驱动Firefox 28.0在应用内购买平台上进行一些基本的购买检查。由于以下
，测试在大约30％的时间内失败File "/path/Steps/do_something.py", line 19, in main
selenium_tearDown.tearDown(driver)

CannotSendRequest
测试试图关闭浏览器窗口，但未能这样做。
只有在我们的Jenkins机器上运行测试时才会出现此错误，因此当我在本地进行测试时，我不会遇到同样的错误。两个环境都是相同的，并运行相同版本的selenium，firefox等。
此问题似乎发生在以前版本的selenium中，但应该已在2.39中修复。我已经尝试回滚到2.39但是我们使用自定义浏览器配置文件然后开始失败。
有没有人有任何建议？
