WebDriverException on clean install

[Naimadnap]

I try to run simple test from /test directory and I get an error like

~/needle/tests$ nosetests3 test_driver.py --with-save-baseline
...EE

To me this looks like a potential bug with Selenium itself. Which version of Selenium are you using, and have you tried upgrading to the latest version?

[Naimadnap]

Selenium 3.0.2 version
Firefox in 50.1
python 2.7.12 and 3.5.2
nosetest 1.3.7
ubuntu 16.04 on virtual box

Thanks. My gut feeling is that it's a bug with the Selenium package with regard to Firefox. I haven't had a chance to test firsthand yet though. On a side note, it'd be useful to add Firefox to the Travis test matrix — I've created a separate issue for that in #60.

this is not going to work in firefox using geckodriver, since the Actions class is yet to be implemented. I think the only temporary solution would be to use selenium 2.x

Ran into this issue, this is related to a bug with Geckodriver and Selenium:
mozilla/geckodriver#548
mozilla/geckodriver#159

A temporary fix for this issue is to downgrade to Selenium 2.53.6 and firefox 45.6. There may be other version combinations that work but in the meantime these have worked for me.

This should be fixed with the code now in master (support was added for Geckodriver and recent Firefox versions).
