Python Splinter browser = Browser() not working
Question: I am trying to use splinter to test my webapp. When I try to execute the
following

    
    
    >>> from splinter import Browser
    >>> browser = Browser()
    

I get this error. I have been looking around but I'm not sure how to fix.
Could someone please tell me how to get past this?

Answer: Here's the code from `firefox_binary.py` that is throwing:

Do you have Firefox installed and working properly? I would also try updating
Firefox to make sure it's on the latest version.
