do some webdriver stuff in Firefox... save screenshot on any exception to a dated image file:

browser = webdriver.Firefox()

try:
    # do some webdriver stuff here
except Exception as e:
    print e
    now = datetime.now().strftime('%Y-%m-%d_%H-%M-%S')
    browser.get_screenshot_as_file('screenshot-%s.png' % now)
