I use Firefox containers to be logged into 3 AWS accounts and works fine for me.

Correct; your AWS session would be scoped to your profile. You could be using your own personal account in the "Personal" profile, and your professional/corporate account in your "Work" profile.
I've tried this in Multi-Account Containers for Firefox and SessionBox in Chrome, and they're both pretty buggy, e.g. the console's username menu indicates I'm in account "A", but I'm seeing resources listed from account "B", or EC2 will work fine but clicking over to ECS prompt me to sign in again.
