[Pritam Kalbhor]

I am using selenium in following environment:

OS: Ubuntu: 20.04

Selenium: 4.1.0

Browser: Firefox 94.0

Geckodriver: 0.30

Python: 3.8+

I am running following commands:
from selenium import webdriver
from selenium.webdriver.firefox.options import Options
options = Options()
options.headless = True
browser = webdriver.Firefox(options=options)
url = 'https://www.google.com'
browser.get(url)

I am getting the following error:

browser.get(url)
