This is one of the "killer features" for me that have me use Firefox. And when I upgraded to FF 103 it was removed along with all my containers! :-(

All it takes to lose every single bit of personalized configuration is to toggle disable by accident once.

And I thought it was supposed to sync the settings back regardless?

I'm done with containers. Great idea, poorly implemented.

Excellent feature!

Very good

It a nice feature to be able to contain different services. But it is missing more controls. E.g. I don't see a option to be able to remove container association for a service.

Does everything I wanted... a great fit !!!

Perfect

It's very useful. pls add option that let us open all containers in same time.

Works perfectly! Saves separate logins and sessions or different containers

proxy not work

Great start, but few things that are broken in an annoying way. For example, "Remember my choice for this website" never works if you select the non-highlighted option (no container). Also there's no way to edit or change these defaults once you selected them if you're not a developer and you're not ready to dig in the local storage of debugging the addon view.

There should be a shortcut to open a new tab in current container without using mouse.

Really very useful feature.
