Intuitive, straightforward and very effective. Using the containers is an easy safety habit to build. Great add-on.

The latest version (8.0.7) is even worse than last time I tested this extension: still no wildcards support, horrible performance, and ads for Mozilla VPN: one at install, another one after opening the popup, and yet another one when managing a container...

Fantastic app to keep separated profiles. It takes sometime to sort out with site in in which container, but afterwords, it's great.

Love the feature, I like having multiple accounts setup in different containers, keeping work/private separate.
And it's great for testing as different users when developing code.

Mozilla didn't merge https://github.com/mozilla/multi-account-containers/pull/1500
