login state with signInWithCustomToken shared with browser tabs

[taketomatsunaga]

Hi

I have an application built with angular fire. How can I not share login state among tabs in a same browser ?

Application overview

I have a class 'FireService' to login with custom token. And application let users to login two ways 'as account owner' or 'as public user'. And if an account owner logins, FireService#login method will be called. And if a public user logins, FireService#loginAsPublicUser method will be called.

Issue

With same browser but different tab, login as an account owner in a tab 'A' and login as a public user in a tab 'B', the login state was overridden with the public users's and he gets an error due to insufficient permission of firebase rules. Because the owner was trying to access as the public user and blocked by my firebase rules.

I checked the browsers log, after the account owner's stats was overridden, the authorization headers value to start session with firestore was the public user's not the account ownser's. How can I use login state separately for users different tabs in a same browser?
