Earlier this test was working fine. But I don't know what happened suddenly to firefox?

I am using Mozilla Firefox for Ubuntu 47.0 and Python 2.7.6

Use FF46. Install it anywhere and set it up with something like

    binary = FirefoxBinary(....where is the ff bin ....)
    driver = webdriver.Firefox(firefox_binary=binary)
