Containers does not work for Microsoft sites
So today I wanted to try FF Containers, because I have service user to manage O365, my normal company user and my personal user.
Now I open make.powerapps.com in container dedicated to this site I log in with one of these users everything is ok, but during first sign-in I am not asked even for password for specified account, I just enter email and then I am redirected and signed in. I have disabled "Allow Windows single sign-on for Microsoft, work, and school accounts". When I want to access portal.azure.com in another container, I am automatically signed in with user from previous container dedicated to powerapps.
I especially logged out of all containers and removed all cookies from FF before submitting and it is still happening
Also checked Windows "Internet options", I do not have any of these sites in "Intranet sites" and Level for all zones regarding to User Authentication is "Prompt for user name and password" dunno know what is wrong.

It is difficult to set up a container when a site routinely traverses multiple servers. Just using office.com you'll need access to scripts from multiple sites and of course, you log on using a completely different site. Maybe someone has published a list somewhere of all the sites you'll need to put into the container to get it to work.
