selenium.common.exceptions.WebDriverException: Message: Process unexpectedly closed with status 1

Start at instapy/instapy.py line 325 and instapy/browser.py line 123, following the Selenium Firefox WebDriver session startup shown in the traceback. Reproduce the Firefox launch failure and determine the cause of the process exiting with status 1; done means the quickstart can create the browser session without this exception.
