Невозможно правильно загрузить firefox с селеном

Question

Я новичок в программировании и, вероятно, в Python2 я получил ошибку при попытке загрузить Firefox с селеном, пожалуйста, как я могу исправить эту ошибку?Я работаю на Windows 7 64bit, Python2.7, Firefox58.Вот код ниже:

    from selenium import webdriver
    import time
    p = proxy
    pp = port
    ua = user_agent
    fp = webdriver.FirefoxProfile()
    fp.set_preference("network.proxy.type", 1)
    fp.set_preference("network.proxy.http",p)
    fp.set_preference("network.proxy.http_port",pp)
    fp.set_preference("network.proxy.ssl",p)
    fp.set_preference("network.proxy.ssl_port",pp)
    fp.set_preference("general.useragent.override",ua)
    fp.set_preference("media.peerconnection.ice.proxy_only", True)
    fp.update_preferences()
    driver = webdriver.Firefox(firefox_profile=fp)

    driver.get(url)
    time.sleep(5)
    driver.quit()

driver = webdriver.Firefox(firefox_profile=fp)
