How to make firefox headless programmatically in Selenium with python?
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")
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
$ 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
