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")

I tried your code and set property marionette to false or else it will not load Firefox portable 65 but it never navigates to the page! Could you help me ?thanks — user1788736, Mar 17 '19 at 00:00
