[keycloak-user] Kerberos & login, multiple environments with multiple users

I think whether or not session cookies are shared between browser tabs is browser specific, but in Firefox I believe they are shared.  You can create separate Firefox "profiles" to get around it:

I am not sure I understand correctly, but generally, Keycloak is browser 
SSO and being logged in 2 browser tabs in 2 clients as different user is 
something generally unsupported and can cause various kind of issues. If 
you want something like this just for development, you can maybe use 
different realms?
