How to make Firefox headless programmatically in Selenium with Python?
PythonPython 3.xSeleniumSelenium WebdriverFirefox HeadlessPython Problem Overview
I am running this code with python, 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")

Solution 1 - Python
To invoke Firefox Browser headlessly, you can set the headless
property through Options()
class as follows:
from selenium import webdriver
from selenium.webdriver.firefox.options import Options
options = Options()
options.headless = True
driver = webdriver.Firefox(options=options, executable_path=r'C:\Utility\BrowserDrivers\geckodriver.exe')
driver.get("http://google.com/")
print ("Headless Firefox Initialized")
driver.quit()
There's another way to accomplish headless mode. If you need to disable or enable the headless mode in Firefox, without changing the code, you can set the environment variable MOZ_HEADLESS
to whatever if you want Firefox to run headless, or don't set it at all.
This is very useful when you are using for example continuous integration and you want to run the functional tests in the server but still be able to run the tests in normal mode in your PC.
$ MOZ_HEADLESS=1 python manage.py test # testing example in Django with headless Firefox
or
$ export MOZ_HEADLESS=1 # this way you only have to set it once
$ python manage.py test functional/tests/directory
$ unset MOZ_HEADLESS # if you want to disable headless mode

Solution 2 - Python
The first answer does't work anymore.
This worked for me:
from selenium.webdriver.firefox.options import Options as FirefoxOptions
from selenium import webdriver
options = FirefoxOptions()
options.add_argument("--headless")
driver = webdriver.Firefox(options=options)
driver.get("http://google.com")
Solution 3 - Python
My answer:
set_headless(headless=True) is deprecated.
options.headless = True
works for me
Solution 4 - Python
Used below code to set driver type based on need of Headless / Head for both Firefox and chrome:
// Can pass browser type
if brower.lower() == 'chrome':
driver = webdriver.Chrome('..\drivers\chromedriver')
elif brower.lower() == 'headless chrome':
ch_Options = Options()
ch_Options.add_argument('--headless')
ch_Options.add_argument("--disable-gpu")
driver = webdriver.Chrome('..\drivers\chromedriver',options=ch_Options)
elif brower.lower() == 'firefox':
driver = webdriver.Firefox(executable_path=r'..\drivers\geckodriver.exe')
elif brower.lower() == 'headless firefox':
ff_option = FFOption()
ff_option.add_argument('--headless')
ff_option.add_argument("--disable-gpu")
driver = webdriver.Firefox(executable_path=r'..\drivers\geckodriver.exe', options=ff_option)
elif brower.lower() == 'ie':
driver = webdriver.Ie('..\drivers\IEDriverServer')
else:
raise Exception('Invalid Browser Type')
Solution 5 - Python
To the OP or anyone currently interested, here's the section of code that's worked for me with firefox currently:
opt = webdriver.FirefoxOptions()
opt.add_argument('-headless')
ffox_driver = webdriver.Firefox(executable_path='\path\to\geckodriver', options=opt)
Solution 6 - Python
from selenium.webdriver.firefox.options import Options
if __name__ == "__main__":
options = Options()
options.add_argument('-headless')
driver = Firefox(executable_path='geckodriver', firefox_options=options)
wait = WebDriverWait(driver, timeout=10)
driver.get('http://www.google.com')
Tested, works as expected and this is from Official - Headless Mode | Mozilla
