selenium问题是只能打开firefox浏览器，不能访问网址。

我的问题也是一样，浏览器能打开，但是打开之后就没反应了
selenium-2.33.0
firefox 21.0
-----------------------------
# coding = utf-8
from selenium import webdriver

browser = webdriver.Firefox()

browser.get("http://www.baidu.com")
browser.find_element_by_id("kw").send_keys("selenium")
browser.find_element_by_id("su").click()
browser.quit()
下面是我发现的一些错误日志
