如何让多个selenium浏览器同时运行？

from selenium import webdriver
import threading

def run_browser(url, browser_type):
    if browser_type == 'chrome':
        driver = webdriver.Chrome()
    elif browser_type == 'firefox':
        driver = webdriver.Firefox()
    else:
        raise ValueError("Unsupported browser type")
    
    driver.get(url)
    print(f"{browser_type} browser opened and navigated to {url}")
    # 这里可以添加更多的操作
    driver.quit()

# 定义要打开的URL和浏览器类型
urls = ['http://example.com', 'http://example.org']
browser_types = ['chrome', 'firefox']

# 创建并启动线程
threads = []
for url, browser_type in zip(urls, browser_types):
    thread = threading.Thread(target=run_browser, args=(url, browser_type))
    threads.append(thread)
    thread.start()

# 等待所有线程完成
for thread in threads:
    thread.join()

from selenium import webdriver
import multiprocessing

def run_browser(url, browser_type):
    if browser_type == 'chrome':
        driver = webdriver.Chrome()
    elif browser_type == 'firefox':
        driver = webdriver.Firefox()
    else:
        raise ValueError("Unsupported browser type")
    
    driver.get(url)
    print(f"{browser_type} browser opened and navigated to {url}")
    # 这里可以添加更多的操作
    driver.quit()

# 定义要打开的URL和浏览器类型
urls = ['http://example.com', 'http://example.org']
browser_types = ['chrome', 'firefox']

# 创建并启动进程
processes = []
for url, browser_type in zip(urls, browser_types):
    process = multiprocessing.Process(target=run_browser, args=(url, browser_type))
    processes.append(process)
    process.start()

# 等待所有进程完成
for process in processes:
    process.join()
