Python, Selenium: How to specify which sites can load images?

In Selenium chromdriver, we can disable images in this way:

from selenium import webdriver

chrome_options = webdriver.ChromeOptions()
prefs = {"profile.managed_default_content_settings.images": 2}
chrome_options.add_experimental_option("prefs", prefs)
driver = webdriver.Chrome(chrome_options=chrome_options)

But this method disables images on all sites. In Google Chrome, you can separately specify a list of sites to which images can be loaded.

Is it possible to do this with Selenium?

Solution

  • No, you won't be able to configure ChromeOptions differently per site unless you reinitialize ChromeDriver and

    When you configure an instance of a ChromeDriver using ChromeOptions() in the process of initiating a new Chrome Browsing Session the configuration gets baked into the ChromeDriver service instance and will persist till the lifetime of the WebDriver being uneditable. So you can't add any further ChromeOptions to the WebDriver instance which is currently in execution.

    Even if you are able to extract the ChromeDriver and ChromeSession attributes e.g. Session ID, Cookies, UserAgent and other session attributes from the already initiated ChromeDriver and Chrome Browsing Session still you won't be able to change the set of attributes of the ChromeDriver.

    A cleaner way would be to call driver.quit() within tearDown(){} method to close and destroy the current ChromeDriver and Chrome Browser instances gracefully and then span a new set of ChromeDriver and Chrome Browser instance with the new set of configurations.
