How can you combine FirefoxOptions with a custom profile to disable images loading and run headless in Selenium Python?
Aoptions = webdriver.FirefoxOptions() options.add_argument('--disable-images') options.headless = True driver = webdriver.Firefox(options=options)
Bprofile = webdriver.FirefoxProfile() profile.set_preference('images.enabled', False) options = webdriver.FirefoxOptions() driver = webdriver.Firefox(profile=profile, options=options)
Cprofile = webdriver.FirefoxProfile() profile.set_preference('permissions.default.image', 2) options = webdriver.FirefoxOptions() options.headless = True driver = webdriver.Firefox(firefox_profile=profile, options=options)
Doptions = webdriver.FirefoxOptions() options.set_preference('permissions.default.image', 2) options.headless = True driver = webdriver.Firefox(options=options)
Step-by-Step Solution
Solution:

  1. Step 1: Disable images using FirefoxProfile

    Set 'permissions.default.image' to 2 in FirefoxProfile to block images.

  2. Step 2: Enable headless mode via FirefoxOptions

    Set options.headless = True to run Firefox headless.

  3. Step 3: Pass both profile and options to Firefox driver

    Use firefox_profile=profile and options=options parameters together.

  4. Final Answer:

    profile = webdriver.FirefoxProfile()\nprofile.set_preference('permissions.default.image', 2)\noptions = webdriver.FirefoxOptions()\noptions.headless = True\ndriver = webdriver.Firefox(firefox_profile=profile, options=options) -> Option C

  5. Quick Check:

Quick Trick: Use FirefoxProfile for prefs, FirefoxOptions for headless [OK]
