Hands down one of the most useful Firefox Add-ons the the Firefox universe!

Es el mejor Add-On para gestionar varias cuentas de usuario en el mismo navegador. Ahorra tiempo, es seguro y sencillo.

The single most useful extension in existence. It's a must have.

Great plugin, use it all the time, but has developed a nasty habbit of NOT remembering my choices about "always open in xx tab".

This add-on is very useful! I would just like to suggest that the container button be implemented replacing the new tab (plus button) making it easier for users to choose the container type of the new tab.

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.
