Python/Selenium incognito/private mode

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:

--incognito Causes the browser to launch directly in incognito mode.

from selenium import webdriverchrome_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 webdriverfirefox_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:

Note: chrome_options is now deprecated. We can use 'options' instead of chrome_options

from selenium import webdriveroptions = webdriver.ChromeOptions()options.add_argument("--incognito")driver = webdriver.Chrome(options=options)driver.get('https://google.com')

I have initiated both Chrome and Firefox in incognito/Private mode using ChromeOptions and FirefoxOptions successfully using the code snippets in Java as below:

    //For Firefox    FirefoxOptions options = new FirefoxOptions();    options.addArguments("-private");    DesiredCapabilities caps = new DesiredCapabilities();    caps.setCapability("moz:firefoxOptions",options);    //For Chrome    ChromeOptions options = new ChromeOptions();    options.addArguments("-incognito");    caps.setCapability(ChromeOptions.CAPABILITY, options);    WebDriver driver = new RemoteWebDriver(new URL(URL), caps);
