推荐答案

使用Python 3.6.2，Selenium 3.5.0和GeckoDriver 0.18.0且Firefox浏览器版本在Windows 7上是54.0.1时，您将无法将属性marionette设置为False.强制将marionette设置为False将引发WebDriverException.因此，您要么必须接受默认设置 ["marionette"] = True ，要么可以将 ["marionette"] 显式设置为 True ，如下所示:

When you work with Python 3.6.2, Selenium 3.5.0 with GeckoDriver 0.18.0 and the Firefox browser version is 54.0.1 on Windows 7, you can't set the property marionette to False. Forcefully setting marionette to False will raise an WebDriverException. So either you have to accept the default setting of ["marionette"] = True or you can explicitly set ["marionette"] to True as follows:

from selenium import webdriver
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary

capabilities = webdriver.DesiredCapabilities().FIREFOX
capabilities["marionette"] = True
binary = FirefoxBinary('C:/Program Files/Mozilla Firefox/firefox.exe')
driver = webdriver.Firefox(firefox_binary=binary, capabilities=capabilities, executable_path="C:/Utility/BrowserDrivers/geckodriver.exe")
driver.get("http://www.google.com")
