Works out of the box just like a charm, though also extremely configurable in conjunction with Simple Tab Groups. A must have!

this is that I have been waiting from some time

Exactly the functionality I've been waiting for for a long time! Works great!

I think it most useful addon for developers! Right now I don't need to keep second browser while testing different users.

This extension is just so much useful. Firefox + this extension = Google does not record NOTHING of your online activity or history

Perfect concept for our actual way of connecting to the web !

perfect for separating my school, work, and personal emails, as well as managing my logins on websites where I have multiple accounts. Intuitive, streamlined, and reliable.

This addon has a lot of potential, and it could have many interesting features like setting or displaying user-agent, cookies and history independently for each container.

I hope it will be maintained and more advanced features will be added.

The #1 feature that keeps me using Firefox. The ability to keep personal info sucking websites walled off in their own sandbox is invaluable.

Very useful, would be useful to be able to have different instances of extensions in different containers to set different privacy settings for example, but I imagine this would be difficult to implement.

Muito prático, eficiente e simples de usar!

Este add-on me ayudo a mantener sesiones separadas de todas las cuentas que tengo de G Suite. Creo que es mejor alternativa que tener múltiples perfiles, por el tema del consume de RAM.
