User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:65.0) Gecko/20100101 Firefox/65.0
Steps to reproduce:
- Open a firefox mozilla browser window in private browsing mode (New Private Window).
- Login into gmail service
- Open one more "New Private window" browser and if we go to gmail it takes us inside the gmail session opened in step 2 without login.
From one private window browser we are able to get the sessions created in another private window browser. I am able to go to the same gmail session of one private window browser in another private window browser. There is no privacy among the private windows of the browser.
The session information from one private window of the Firefox browser should not be visible to the other private window of the Firefox browser. So If I am opening a gmail account in one private window, it should not be visible in another private browser window.
