Python: Selenium Firefox Webdriver failing with error: 'Can't load the profile...WARN addons.xpi..."
提问by duhaime
I am trying to run the following Python code to create a Firefox Webdriver window via Selenium:
我正在尝试运行以下 Python 代码以通过 Selenium 创建 Firefox Webdriver 窗口：
from selenium import webdriver
driver = webdriver.Firefox()
driver.get("http://www.google.com")
While this code worked fine a few weeks ago, it now produces the following foreboding message:
虽然此代码在几周前运行良好，但现在会产生以下不祥信息：

Does anyone know what this means, or what I can do to remedy the error and get the code to run as expected? I've found related error messages through Google searches, but nothing that has allowed me to resolve the issue.
有谁知道这意味着什么，或者我可以做些什么来纠正错误并使代码按预期运行？我通过谷歌搜索找到了相关的错误消息，但没有任何东西可以让我解决这个问题。
For what it's worth, I can open a Chrome Webdriver without issue by changing the second line of the above to driver = webdriver.Chrome().
对于它的价值，我可以通过将上面的第二行更改为driver = webdriver.Chrome().
I'm using Python 2.7, Selenium 2.35.0 (I just ran "pip install selenium --upgrade) and Firefox 26.0 on a Windows 8 machine. Any tips or advice others can offer are most appreciated.
我在 Windows 8 机器上使用 Python 2.7、Selenium 2.35.0（我刚刚运行了“pip install selenium --upgrade”）和 Firefox 26.0。非常感谢其他人可以提供的任何提示或建议。

Selenium 2.35 is not compatible with Firefox 26. As the release notessay, FF 26 support was added in Selenium 2.39. You need to update to 2.39. Try pip install -U seleniuminstead.
Selenium 2.35 与 Firefox 26 不兼容。正如发行说明所说，在 Selenium 2.39 中添加了 FF 26 支持。您需要更新到 2.39。试试吧pip install -U selenium。

Not sure if it works fine on Windows too, but for me the combination of Firefox 26 and selenium 2.37.0 works fine.
不确定它在 Windows 上是否也能正常工作，但对我来说，Firefox 26 和 selenium 2.37.0 的组合工作正常。

I also have this issue in Win8.1 FF28 and python3.4/selenium 2.41. But after I degraded FF to 24, it worked! And I also tested in Win8.1/FF27/Python3.4/Selenium 2.41, it worked too.
我在 Win8.1 FF28 和 python3.4/selenium 2.41 中也有这个问题。但是在我将 FF 降级到 24 之后，它起作用了！而且我还在 Win8.1/FF27/Python3.4/Selenium 2.41 中进行了测试，它也有效。
