New private window remembers office.com login credentials from previous window

I have to do administration work in several Office.com tenants. When using Safari I am able to start a new private window, visit office.com and forced to provide login credentials. With this I can be logged in to multiple tenants at one time. This is expected behavior.

When I open a new private window (FireFox 69.0) and go to office.com the login credentials I am currently using are remembered from my previous private window, and I am already logged in to office.com in the new private window. This is not expected behavior.

If I understand things correctly every time I start a new private window I should be required to provide credentials each time I visit office.com for the first time in that new private window. Right?

hi, firefox doesn't isolate private windows among each other - they share the same cookies & login states.

if you want to log-into the same site with different accounts, mozilla's container addon is the right tool for the job: https://addons.mozilla.org/firefox/addon/multi-account-containers/
