Amazing tool! I manage several different Office 365 tenants and this allows me to setup admin and test user profiles for each without having to open private tabs or use multiple browsers.

Excelent!

Excellente extension pour gérer un même site ouvert avec plusieurs comptes en même temps. Super intuitif, pratique et fonctionnel, bravo !

awesome add-on!

Works like a charm!

I develop apps which require multiple sessions with a role each, this addon has made my life easier

Très pratique pour gérer plusieurs emails !

Love this tool. Use it daily and makes sign in to different accounts so much easier

Very Helpful to keep myself organized.

really awesome feature, well done. intuitive UI. found it very easy to use and super helpful in my day-to-day workflow.

Love it. I can now use the same browser under 3 different credentials. My work account, my work-admin account, and my personal account. All from the same browser. Don't think any other browser can do that, yet.

I was looking for such function for a long time and this extension was the Gold Mine !!

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.
