Threading and Selenium

I'm trying to make multiple tabs in Selenium and open a page on each tab simultaneously. Here is the code.

CHROME_DRIVER_PATH = "C:/chromedriver.exe"

from selenium import webdriver
import threading
driver = webdriver.Chrome(CHROME_DRIVER_PATH)

links = ["https://www.google.com/",
         "https://stackoverflow.com/",
         "https://www.reddit.com/",
         "https://edition.cnn.com/"]

def open_page(url, tab_index):
    driver.switch_to_window(handles[tab_index])
    driver.get(url)
    return

# open a blank tab for every link in the list
for link in range(len(links)-1 ): # 1 less because first tab is already opened
    driver.execute_script("window.open();")

handles = driver.window_handles # get handles

all_threads = []
for i in range(0, len(links)):
    current_thread = threading.Thread(target=open_page, args=(links[i], i,))
    all_threads.append(current_thread)
    current_thread.start()

for thr in all_threads:
    thr.join()


Execution goes without errors, and from what I understand this should logically work correctly. But, the effect of the program is not as I imagined. It only opens one page at a time, sometimes it doesn't even switch the tab... Is there a problem that I'm not aware of in my code or threading doesn't work with Selenium?

There is no need in switching to new window to get URL, you can try below to open each URL in new tab one by one:

links = ["https://www.google.com/",
         "https://stackoverflow.com/",
         "https://www.reddit.com/",
         "https://edition.cnn.com/"]

# Open all URLs in new tabs
for link in links:
    driver.execute_script("window.open('{}');".format(link))

# Closing main (empty) tab
driver.close()

Now you can handle (if you want) all the windows from driver.window_handles as usual
