AttributeError: 'Options' object has no attribute 'binary' error invoking Headless Firefox using GeckoDriver through Selenium

options = FirefoxOptions()
options.add_argument("--headless")


driver = webdriver.Firefox(firefox_options=options, executable_path='/Users/toprak/Desktop/geckodriver') 
driver.get("https://twitter.com/login?lang=en")

When I try to run my code, I get this error:

Warning (from warnings module):
  File "/Users/toprak/Desktop/topla.py", line 19
    driver = webdriver.Firefox(firefox_options=options, executable_path='/Users/toprak/Desktop/geckodriver')
DeprecationWarning: use options instead of firefox_options
Traceback (most recent call last):

    if options.binary is not None:
AttributeError: 'Options' object has no attribute 'binary'

When I delete the lines which are about options and take out "firefox_options=options", the code works fine. What should I do to fix this?

Solution

  • Instead of using firefox_options object you need to use options object. Additionally you need to use the headless attribute. So your effective code block will be:

    options = FirefoxOptions()
options.headless = True

driver = webdriver.Firefox(executable_path='/Users/toprak/Desktop/geckodriver', options=options) 
driver.get("https://twitter.com/login?lang=en")
