我的普通窗口中的Cookie在隐身窗口或任何其他窗口中不起作用

I know that websites store cookies to validate users on different websites of the same domain , but when I tried to replicate it on my gmail account it didn't work.

I am using editthiscookie to export and then import cookies in the incognito browser .

Theoretically the browser should log me into my gmail account but it doesn't happen.

I had read it somewhere that the servers on the backend check the ip , but that shouldn't be the problem as it's my own PC both the time.

So what's wrong going on ??

Note:

1. EditThisCookie shows all the cookies including 'HttpOnly' and 'Secure'

2. I haven't logged off from my account on the other browser session i.e. the normal session (in case anyone might think of cookie expiration ).

Incognito mode operates as a clean slate, it does not have access to cookies from normal mode.
