Headless mode fails since Selenium 4.12.0

[robgjansen]

Minimal headless test script:

import tbselenium.common as cm
from tbselenium.tbdriver import TorBrowserDriver
from tbselenium.utils import launch_tbb_tor_with_stem

tbb_dir = "/home/test/tor-browser/"
tor_process = launch_tbb_tor_with_stem(tbb_path=tbb_dir)

with TorBrowserDriver(
        tbb_path=tbb_dir,
        executable_path="/home/test/geckodriver",
        tbb_logfile_path="/home/test/tbb.log",
        headless=True, 
        tor_cfg=cm.USE_STEM) as driver:
    driver.load_url("https://check.torproject.org")

tor_process.kill()

Running this with geckodriver-v0.31.0-linux64 and tor-browser-13.0.6.

The test script fails

selenium.common.exceptions.WebDriverException: Message: Process unexpectedly closed with status 1

Using selenium versions 4.16.0, 4.15.0, 4.14.0, and 4.13.0 all failed with the above error, but downgrading selenium to 4.12.0 finally worked for me:

pip remove selenium
pip install "selenium==4.12.0"
