How do you correctly configure Firefox WebDriver to run in headless mode using Selenium in Python?

Aoptions = webdriver.FirefoxOptions(); options.add_argument('--headless'); driver = webdriver.Firefox(options=options)

Boptions = webdriver.FirefoxOptions(); options.headless = True; driver = webdriver.Firefox(options=options)

Coptions = webdriver.FirefoxOptions(); options.set_preference('headless', True); driver = webdriver.Firefox(options=options)

Ddriver = webdriver.Firefox(); driver.set_headless(True)

Step-by-Step Solution

Solution:

Step 1: Create FirefoxOptions object
This object allows setting browser-specific options.
Step 2: Enable headless mode
Set the headless attribute to True to run Firefox without UI.
Step 3: Pass options to Firefox WebDriver
Instantiate webdriver.Firefox with the configured options.
Final Answer:
options = webdriver.FirefoxOptions(); options.headless = True; driver = webdriver.Firefox(options=options) -> Option B
Quick Check:
Using options.headless = True is the recommended way [OK]

Quick Trick: Set options.headless = True for Firefox headless mode [OK]

Common Mistakes:

Using add_argument('--headless') with FirefoxOptions (works for Chrome, not Firefox)
Trying to set headless mode via set_preference (not valid)
Calling driver.set_headless(True) which is not a valid method
