webdriver调用firefox失败

[tornadoltm]

用webdriver调用firefox失败，版本：selenium IDE 2.5.0 firefox 17.0
能打开浏览器，但是无法get “www.baidu.com”
请问这是什么原因呢？急

代码
require 'rubygems'
require 'selenium-webdriver'

driver = Selenium::WebDriver.for :ff
driver.get "http://www.baidu.com"
sleep 3

puts driver.title
driver.quit

错误信息

我也遇到了！你解决了吗？

127.0.0.1 localhost 在host文件第一行加上这个试试，我这之前也总是超时，这样设置后就好了
