在我的Ubuntu工作站上本地运行使用Firefox的Selenium（Webdriver）测试不再有效。
以前完全相同的设置工作，但我认为Firefox在某个时候升级了（现在它是Ubuntu包16.0.2+build1-0ubuntu0.11.04.1的16.0.2），之后它停止了工作。在正常使用中，Firefox工作正常。
使用Webdriver，当我运行测试用例（通过我的IDE）时，会打开一个空的Firefox窗口，但测试无法启动。 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:

在我们的基础测试课程中，FirefoxDriver的初始化方式如下：
new FirefoxDriver(new FirefoxProfile())
...虽然我也尝试使用相同的结果指向现有的Firefox配置文件目录（类似/home/jonik/.mozilla/firefox/vds3ono5.default）。
如何让测试再次运行？
答案 0 :(得分：5)
v2.23不支持Firefox 16。您必须升级到v2.26，或降级Firefox。
