Отказано в доступе при загрузке Firefox в GeckoDriver

Question

Я получил «PermissionError: [Errno 13] Отказано в разрешении:« firefox »» при запуске файла скреппера в python3

from selenium import webdriver
from selenium.webdriver.firefox.options import Options
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary

options = Options()
options.add_argument('--headless')
options.add_argument('--disable-gpu')

binary = FirefoxBinary('firefox')
cap = DesiredCapabilities().FIREFOX
cap["marionette"] = False
driver = webdriver.Firefox(executable_path='geckodriver', options=options, capabilities=cap, firefox_binary=binary)

Но потом я получил:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
