First of all, since selenium by default starts up a browser with a clean, brand-new profile, you are actually already browsing privately. Referring to:
- Python – Start firefox with Selenium in private mode
- How might I simulate a private browsing experience in Watir? (Selenium)
But you can strictly enforce/turn on incognito/private mode anyway.
For chrome pass --incognito command-line argument:
--incognitoCauses the browser to launch directly in incognito mode.
from selenium import webdriver
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument("--incognito")
driver = webdriver.Chrome(chrome_options=chrome_options)
driver.get('https://google.com')
FYI, here is what it would open up:
For firefox, set browser.privatebrowsing.autostart to True:
from selenium import webdriver
firefox_profile = webdriver.FirefoxProfile()
firefox_profile.set_preference("browser.privatebrowsing.autostart", True)
driver = webdriver.Firefox(firefox_profile=firefox_profile)
FYI, this corresponds to the following checkbox in settings:
