Python selenium error when trying to launch firefox

Question

I am getting an error when trying to open Firefox using Selenium in ipython notebook. I've looked around and have found similar errors but nothing that exactly matches the error I'm getting. Anybody know what the problem might be and how I fix it? I'm using Firefox 22.

The code I typed in was as follows:

from selenium import webdriver
driver = webdriver.Firefox()

The error the code returns is as follows:

    WindowsError                              Traceback (most recent call last)
<ipython-input-7-fd567e24185f> in <module>()

Answer 1

Try specify your Firefox binary when initialize Firefox()

from selenium import webdriver
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary

binary = FirefoxBinary('path/to/binary')
driver = webdriver.Firefox(firefox_binary=binary)

The default path FirefoxDriver looking for is at %PROGRAMFILES%\Mozilla Firefox\firefox.exe. See FirefoxDriver

Or add your path of Firefox binary to Windows' PATH.
