How to load firefox profile with Python Selenium?

Question

I\'m trying to get Python Selenium to work on my Windows Machine. I\'ve upgraded to the latest versions of Firefox, Selenium, Geckodriver, but I still receive the below error: <

Solution:

from selenium import webdriver
fp = webdriver.FirefoxProfile('/home/gabriel/.mozilla/firefox/whatever.selenium')
driver = webdriver.Firefox(fp)

I struggled until I found this issue which is now solved but was helpful because it shows some commands.

first version, not working because I could not connect with selenium afterward:

from selenium.webdriver.firefox.options import Options
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

options = Options()
options.add_argument("-profile")
options.add_argument("/home/gabriel/.mozilla/firefox/whatever.selenium")
firefox_capabilities = DesiredCapabilities.FIREFOX
firefox_capabilities['marionette'] = True
driver = webdriver.Firefox(capabilities=firefox_capabilities, firefox_options=options)

I am sure that this loads the profile "whatever.selenium" because if I go to about:profiles I can read:

Profile: selenium This is the profile in use and it cannot be deleted.

Even though "whatever.selenium" is not the default profile on my system.

Remark: at least one the profile parameters is overridden by selenium (or geckodriver?): Preferences > Privacy and Security > "Block pop-up windows" is always reseted to off. So use about:profiles to make assertions on which profile you are running.

notes:

• firefox_capabilities might not be needed in above code.
• tested under Firefox 60.4.0esr (64-bit), geckodriver 0.23.0 ( 2018-10-04), selenium 3.141.0 with Python 3.5.3
