Скачайте chromedriver и распакуйте его.
from selenium import webdriver
driver = webdriver.Chrome(executable_path='/home/debian/Downloads/chromedriver')
Работает нормально. Теперь, чтобы протестировать geckodriver для firefox, моя версия firefox - 78.0.2 (64-разрядная), последняя версия, я загрузил geckodriver-v0.26.0-linux64.tar.gz и извлек его.
from selenium import webdriver
driver = webdriver.Firefox(executable_path='/home/debian/Downloads/geckodriver')
Он обнаруживает некоторые проблемы:
Traceback (most recent call last):
