将Python中的Selenium与Firefox结合使用时，driver.close（）会占用一秒钟来执行

Question

我运行的代码将在Firefox中打开一个页面，转到另一个页面，然后关闭。这一切都在循环中运行。打开浏览器（即driver = webdriver.Firefox(options = options)需要10~15秒，这已经够烦人了，但是每三次迭代中有两次driver.close()需要约70秒才能执行，否则只需要3~5秒

我在正常浏览互联网和关闭所有其他应用程序的情况下运行了此测试。有什么方法可以修复此问题吗

我有一个文本文件，其中包含我最近运行的110个测试：如果我只是在这里打印前20个循环，例如：

多亏了“一切提前”。如果有帮助的话，我使用WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.XPATH, "XPATH"))).click()来导航浏览器
