在我的 Ubuntu 工作站上本地使用 Firefox 运行 Selenium (Webdriver) 测试不再有效。
完全相同的设置以前工作过，但我认为 Firefox 在某个时候升级了（现在是 Ubuntu 软件包中的 16.0.2 16.0.2+build1-0ubuntu0.11.04.1），之后它停止工作。在正常使用中，Firefox 工作正常。
使用 Webdriver，当我（通过我的 IDE）运行测试用例时，会打开一个空的 Firefox 窗口，但测试没有开始。45 秒后，它会超时并显示以下错误消息：
org.openqa.selenium.firefox.NotConnectedException: Unable to connect to host 127.0.0.1 on port 7055 after 45000 ms. Firefox console output:

在我们的基础测试类中，FirefoxDriver初始化如下：
new FirefoxDriver(new FirefoxProfile())
...尽管我也尝试指向现有的 Firefox 配置文件目录（类似于/home/jonik/.mozilla/firefox/vds3ono5.default），但结果相同。
任何想法如何让测试再次运行？
