Start with good_commenting_strategy_and_new_qs_system.py and trace the failing startup through instapy/instapy.py and instapy/browser.py, following the reported Firefox WebDriver capability error. Reproduce the issue in the documented Python 3.5 setup and confirm completion when the quickstart launches successfully.
