I want to run firefox in headless mode on server but both options.add_argument("--headless") and options.set_headless(headless=True) are not working.
from selenium import webdriver
from selenium.webdriver.firefox.options import Options
print("Executing script")
options = Options()
#options.add_argument("--headless")
options.set_headless(headless=True)
try:
driver = webdriver.Firefox(firefox_options=options,
executable_path="/path-to-driver/geckodriver.exe");
driver.get("https://www.google.com")
print(driver.page_source)
finally:
driver.quit()
print ("Script executed successfully")
I am using Python 3.6.5, Selenium 3.12.0 and firefox 52.8.0 (32-bit).
I don't see any such issue in your code trails. However it seems there is a version mismatch within the binaries you are using as follows:
You are using Selenium 3.12.0 and Firefox v52.8.0.
As per the following discussions:
The milestone for Mozilla Headless Mode was Mozilla v55.0a1
Upgrading your Mozilla Browser Client to Mozilla v55.0a1 or above will address your issue.
