selenium with firefox issue -- firefox doesn't respond despite updates

Question

When I try to run a functional test that opens a browser (Firefox) using Selenium, I get a strange message that I can't make sense of. I've already updated Selenium using pip install --upgrade selenium, as well as re-installed the latest Firefox, and it didn't help. Here's the full text of my error message. Any suggestions?

I would check out the answer here. Easy answer is downgrade firefox or download the marionette webdriver [Can't open browser with selenium after firefox update](http://stackoverflow.com/questions/37761668/cant-open-browser-with-selenium-after-firefox-update) — jharrison12, Jun 16 '16 at 21:27

If you are using FirefoxDriver and you have Firefox 47 installed you should look into using the MarionetteDriver instead because Mozilla is switching to Marionette.
