After calling driver.close()the value of driver is set to
调用driver.close()后驱动的值设置为
FirefoxDriver: firefox on WINDOWS(4b4ffb1e-7c02-4d9c-b37b-310c771492ac)
But if you call driver.quit()then it sets the value of driver to
但是如果你打电话，driver.quit()那么它会将 driver 的值设置为
FirefoxDriver: firefox on WINDOWS (null)
So if you're checking the browser window after calling driver.quit()then you will be able to know by below implementation.
因此，如果您在调用driver.quit()之后检查浏览器窗口，那么您将能够通过以下实现知道。
WebDriver driver = new FirefoxDriver();
driver.get("http://www.google.com");
driver.quit();
if(driver.toString().contains("null"))
{
System.out.print("All Browser windows are closed ");
}
else
{
//open a new Browser
}

There is no api for it. The best one, you can do is call toStringmethod, which returns a string like this:
没有它的api。最好的toString方法是调用方法，它返回一个这样的字符串：
SafariDriver . . . null
Then you can call containsmethod, which does check in the string nullis there.
然后你可以调用contains方法，它会检查字符串null是否存在。
Note that this will work only if the quitis been called.
请注意，这仅在quit被调用时才有效。

I actively use this for Chrome. At the same time, since I run the browsers with cmd title, I can close the command line to get rid of excessive loads.
我积极将其用于 Chrome。同时，由于我用cmd标题运行浏览器，我可以关闭命令行以摆脱过度负载。
from selenium.common.exceptions import WebDriverException
while True:
try:
#do somethings
except selenium.common.exceptions.WebDriverException as e:
if 'chrome not reachable' in str(e):
os.system('taskkill /FI "WindowTitle eq YourTitleIfExistsOrDeleteThisLine*" /T /F')
