Download chromedriver and extract it.

from selenium import webdriver
driver = webdriver.Chrome(executable_path='/home/debian/Downloads/chromedriver')

It works fine.
Now to test geckodriver for firefox,my firefox version is 78.0.2 (64-bit),the latest version,i have downloaded the geckodriver-v0.26.0-linux64.tar.gz and extract it.

from selenium import webdriver
driver = webdriver.Firefox(executable_path='/home/debian/Downloads/geckodriver')

It encounter some issues:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.5/dist-packages/selenium/webdriver/firefox/webdriver.py", line 174, in __init__
    keep_alive=True)
  File "/usr/local/lib/python3.5/dist-packages/selenium/webdriver/remote/webdriver.py", line 157, in __init__
    self.start_session(capabilities, browser_profile)
  File "/usr/local/lib/python3.5/dist-packages/selenium/webdriver/remote/webdriver.py", line 252, in start_session
    response = self.execute(Command.NEW_SESSION, parameters)
  File "/usr/local/lib/python3.5/dist-packages/selenium/webdriver/remote/webdriver.py", line 321, in execute
    self.error_handler.check_response(response)
  File "/usr/local/lib/python3.5/dist-packages/selenium/webdriver/remote/errorhandler.py", line 242, in check_response
    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.SessionNotCreatedException: Message: Unable to find a matching set of capabilities

How to fix it?

first check if selenium are downloaded with no error and make sure that the webdriver are downloaded in the path in this code driver = webdriver.Firefox(executable_path='/home/debian/Downloads/geckodriver')
