firefox - Selenium 在 "Launching Firefox..."停止，没有错误或异常

Question

尝试在我们的 RedHat 机器上远程运行 Selenium 只会停留在“正在启动 Firefox...”，而不会出现任何错误消息。

我有一个从/usr/bin/firefox 到/usr/lib64/firefox/firefox 的符号链接(symbolic link)。 RedHat 机器安装了 Firefox ESR 17.0.6。

我正在使用 Xming 并通过在终端中键入“firefox”来运行 Firefox 工作正常。我尝试通过 Xvfb 运行 Selenium，但它卡在同一个地方(Xvfb 已验证通常与“firefox &”一起工作并截屏)。

以下是终端输入和输出(匿名):

在按下 CTRL+C 之前，我给了它将近 10 分钟。

通过调试，没有更多的事情要做:

关于从哪里开始寻找或任何修复的任何想法？

Answer 1

终于发现问题了。

当我扩展“*firefox”参数以包含 Firefox 的绝对路径(符号链接(symbolic link)显然不起作用)时，Firefox 成功启动。
