I am running this code with Python (http://bit.ly/38YA0O1), selenium, and firefox but still get 'head' version of firefox:

binary = FirefoxBinary('C:\\Program Files (x86)\\Mozilla Firefox\\firefox.exe', log_file=sys.stdout)

binary.add_command_line_options('-headless')

self.driver = webdriver.Firefox(firefox_binary=binary)

I also tried some variations of binary:

binary = FirefoxBinary('C:\\Program Files\\Nightly\\firefox.exe', log_file=sys.stdout) 

       binary.add_command_line_options("--headless")

Like this: 

   options = Options()
   options.headless = True
   driver = webdriver.Firefox(options=options, executable_path='C:\\Program Files(x86)\\Mozilla Firefox\\firefox.exe', log_file=sys.stdout)

or by setting the env var MOZ_HEADLESS: 

   import os
   os.environ["MOZ_HEADLESS"] = "1"
   driver = webdriver.Firefox(executable_path='C:\\Program Files (x86)\\MozillaFirefox\\firefox.exe', log_file=sys.stdout)

I don't think that headless mode works with a profile used for normal mode.

Are you using a special profile for running Firefox in headless mode ?

You need to use the Profile Manager to create the new profile folder, but not launch Firefox (i.e. click Exit). You need to specify this profile via -P "profile-name" command line switch.
