Я использую модуль Python (3.9) Selenium (с последней версией geckodriver 0.29.1) в Windows.

Когда я запускаю этот сценарий

 from selenium import webdriver

firefox_profile = webdriver.FirefoxProfile()
driver = webdriver.Firefox(firefox_profile=firefox_profile)

print("Going into loop")

try:
    while True:
        pass
except KeyboardInterrupt:
    print("Caught exception")
finally:
    print("Finally block")
    driver.get("https://google.com")

print("Got out of loop")
 

Я получаю эту ошибку: (Я нажимаю Ctrl C в ^C)

 PS D:UsersmaartPycharmProjectstestWeb> python3.9 .test.py
Going into loop
^C
Caught exception
Finally block

Почему это происходит? Я сделал этот особый случай, потому что я хочу создать программу, в которой вы можете выйти из бесконечного цикла, нажав Ctrl C, а затем я хочу вызвать driver.quit(). Это приводит к точно такой же ошибке.
