Selenium 服务器将无法远程运行 - 启动 Firefox 时出现问题

Question

我正在努力确定为什么我的 Selenium 测试脚本现在在我的构建服务器上失败，因为它们一直工作到上周。下面的脚本在本地运行良好，但从 Jenkins 运行时出错。我正在运行 Selenium Server (v.selenium-server-standalone-2.21.0.jar)，并试图执行一个简单的登录脚本。

我已经确认没有打开的 Firefox session ，并且我已经删除了所有配置文件以确保没有争用。

这是错误输出:

Firefox 最近更新到 13。你只需要升级到 Selenium 2.23
