I am trying to use Python Selenium to open tabs in the background and do web scraping but I keep running into this error and I don't know what to do

Question

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support.expected_conditions import presence_of_element_located

driver = webdriver.Firefox()
driver.switch_to.new_window('tab')
driver.get('https://www.fbla-pbl.org/fbla-topics/')

the title says it all im really stuck Ive never worked with selenium so I know next to nothing any information would be extremly helpful
