Selenium hangs instantiating FirefoxDriver
提问by stracktracer
I try to get started with selenium (downloaded the current version today) and copied their example which opens a browser and performs a google search.

However, the program hangs forever in the 1st line WebDriver driver = new FirefoxDriver();.
但是，程序永远挂在第一行WebDriver driver = new FirefoxDriver();。
I have Firefox 13 installed.
我安装了 Firefox 13。

These cases are usually when Firefox & Selenium are a little "out of sync" in terms of compatibility.
这些情况通常是 Firefox 和 Selenium 在兼容性方面有点“不同步”。
You should try two things: update Selenium to the latest one and/or downgrade Firefox. Keeping an eye on the Selenium Release Notes
您应该尝试两件事：将 Selenium 更新到最新版本和/或降级 Firefox。密切关注Selenium 发行说明

I've been working OK with Firefox 18, but I just got auto-updated to 19 which seems to break the webdriver. Mozilla isn't prominent with the links to prior versions:
我在 Firefox 18 上工作正常，但我刚刚自动更新到 19，这似乎破坏了 webdriver。Mozilla 与之前版本的链接并不突出：

Saw this behavior when trying to instantiate the webdriver on a headless CentOS server without display being set.
在没有设置显示的情况下尝试在无外设的 CentOS 服务器上实例化 webdriver 时看到了这种行为。
Per https://serverfault.com/questions/363827/how-can-i-run-firefox-on-centos-with-no-display-- you can use Xvfb, which gives you an X server that doesn't require connection to a physical display
根据https://serverfault.com/questions/363827/how-can-i-run-firefox-on-centos-with-no-display- 您可以使用Xvfb，它为您提供不需要的 X 服务器连接到物理显示器

Normally a new browser's hot - I was looking for a problem elsewhere. Webdriver or selenium server. http://d.pr/i/Q5Dt
通常新浏览器很热 - 我在其他地方寻找问题。Webdriver 或 selenium 服务器。http://d.pr/i/Q5Dt
