Works very well. Opening new tabs now exclusively from the multi-account icon.

...

It is a great tool for separating different activities and their related accounts, even more when one has several accounts on the same service, but for different uses (personal/professional, or other).
However, I wish that it be possible to have whole windows be dedicated to one container type, or that there be a shortcut to open a new tab and chose a container for it.

Very usefull and works properly

This should be a core feature of Firefox! The "Always open in " flag is a killer as well. Seamlessly, manages the appropriate containers for the regular sites I visit.

Love this! I have separate containers for each social media site I use, personal, banking, etc.

Achieves a rare combination of convenience and security.

Fantastic for a web developer who needs to be logged in as a user, an admin, and "not logged in" simultaneously in three different tabs. So helpful!

Helps me sort out my life - thanks mozilla!

Can't imagine life without multi-account containers.

Super util, sobre todo para los que necesitamos manejar varias cuentas de google. Por el momento no he encontrado que le falte algo!

La verdad, es que en general es bastante sencilla de usar, al principio solamente tienes que configurar los contenedores, pero de ahí en adelante es un paseo.

Gewoonweg een future die er standaard zou moeten inzitten.
Gebruik deze zelf dagelijks, TOP.

Works well. I now use 1 password manager against multiple "profiles"/containers with ease.

Excellent

good extension
