An awesome addon that makes it easy to isolate work tabs and personal tabs containers allowing you to login into the same site with a different Identity in each container. The ability to give default containers for a site is also super useful.
Areas that require improvement:
Make it easy to edit list of domains to default container associations

Very useful. I like the new features (always open, hide container, etc.)

Очень удобное расширение. Как разработчик, часто приходится тестировать сайты, и контейнеры позволяют не запутаться между тестовым/продакшн сервером, а также помогают хранить раздельные аккаунты на разных сервисах одновременно. Короче, очень удобно)

Houd verschillende zaken makkelijk gescheiden binnen dezelfde browser sessie. Werkt heel goed en makkelijk.
Keep different stuff separated within the same browser session. It works like a charm.

Great
no need profile switcher again

Really useful!

It's perfect. It would be also great to be able to collapse and expand a container.

Una delle migliori estensioni che potessi trovare: posso aprire decine e decine di sessioni separate senza uscire dal browser. Ormai non posso più farne a meno

Es muy buena para mantener las cookies separadas. Tener varias cuentas al mismo tiempo. Mantener la privacidad un poco contralada y las I.A. más productivas. Además de organizar las tareas por colorcitos jaja

开小号很方便，当隐身标签用也很方便

Multi-Account Containers have been one of the best new web-browser features that have been developed in a long time. This is a fantastic way of keeping work projects and personal/work logins separate without having to switch browsers. This allows me to use multiple log-ins to Gmail or AWS while still just switching between Ffox windows or tabs.

Now they just need to make it easier to open/manage tabs in a specific container, and allow the Container settings to sync with a Ffox Account across multiple computers.

Love it!

Hope you can add some buttom on toolbar to open new tab in container for just a buttom!
