From https://forums.gentoo.org/viewtopic.php?p=8845757#8845757 I have problems getting Selenium to work with Firefox in headless mode. It used to work but at some point the past few months it seems to have stopped working. The following script works if I comment out the headless line, otherwise I get the error message below. #!/usr/bin/python from selenium import webdriver options = webdriver.FirefoxOptions() options.add_argument("--headless") driver = webdriver.Firefox(options=options) driver.get("https://google.com") driver.quit() $ ./test hrnick@crow ~/misc $ ./test Traceback (most recent call last): File "/home/hrnick/misc/./test", line 8, in <module> driver = webdriver.Firefox(options=options) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3.12/site-packages/selenium/webdriver/firefox/webdriver.py", line 71, in __init__ super().__init__(command_executor=executor, options=options) File "/usr/lib/python3.12/site-packages/selenium/webdriver/remote/webdriver.py", line 238, in __init__ self.start_session(capabilities) File "/usr/lib/python3.12/site-packages/selenium/webdriver/remote/webdriver.py", line 325, in start_session response = self.execute(Command.NEW_SESSION, caps)["value"] ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3.12/site-packages/selenium/webdriver/remote/webdriver.py", line 380, in execute self.error_handler.check_response(response) File "/usr/lib/python3.12/site-packages/selenium/webdriver/remote/errorhandler.py", line 229, in check_response raise exception_class(message, screen, stacktrace) selenium.common.exceptions.WebDriverException: Message: Process unexpectedly closed with status signal I'm running... Code: dev-python/selenium-4.26.1 dev-util/selenium-manager-4.26.0-r1 www-client/firefox-132.0.1-r1 net-misc/geckodriver-0.35.0-r1 Any ideas what could be wrong? Could the separation of www-client/firefox and net-misc/geckodriver have anything to do with this? Downgrading to firefox-115.16.1-r1 makes the script work but with the following error message: The geckodriver version (0.33.0) detected in PATH at /usr/bin/geckodriver might not be compatible with the detected firefox version (115.16.1); currently, geckodriver 0.35.0 is recommended for firefox 115.*, so it is advised to delete the driver in PATH and retry Any help would be appreciated, thanks! Reproducible: Always Steps to Reproduce: 1. Run the script above Actual Results: This causes an exception Expected Results: The script should run headless Downgrading to firefox-115.16.1-r1 makes the script work as intended. Could the separation of firefox and geckodriver have caused this?
I cannot reproduce the error using the snippet script in #1 (short of the issues seen in bug 913889 i.e. need to set SE_MANAGER_PATH) - perhaps bleeding edge is not compatible with selenium-manager? The script runs and exits with nothing printed. Package versions I currently have installed: www-client/firefox-128.8.0 (which is the ESR) dev-python/selenium-4.29.0 dev-util/selenium-manager-4.29.0 I don't have a geckodriver package installed.
