Very useful, hope it becomes a standard addition to Firefox.

Antes me tocaba abrir ventanas incognitas u otro navegador para abrir cuentas de un mismo servicio sin cerrar sesión.

Teniendo en cuenta que Chrome permite tener múltiples cuenta y abrir sesiones mediante ventanas hacia que uno usuario de Firefox añorara algo así.

Con este plugin no tengo que pensar más en eso.

Funciona cómo indica y me facilita la vida un montón. Se acabaron los días de abrir otro navegador para abrir otra cuenta de una misma web :D

Extremely handy! Like having a private browsing window on steroids.

Firstly, if you are not using Mozilla Firefox as your default browser, you need to see the light! But, idioms aside, the Multi Account Container Add on is a great and easy to use bit of kit. Basically, little sandboxed tabs that keep everything seperate so you can log in, if wanted, to multiple accounts on the same platform. This may be facebook, Gumtree, Amazon etc. Great and thank you all at Mozilla - please continue to help keep the internet inpartial and out of the hands of the greedy corporate b******s that try to steal my life at every click of the mouse. Happy User

Muy conveniente para hacer pruebas con diferentes usuarios en una aplicaciones web.

コンテナーという形式で複垢ができます。
コンテナごとにタブは色分けされており一目瞭然。
また、あるコンテナの全タブに対して新しいウィンドウで開くとか、隠す（一旦閉じて、あとで開けるようにする）機能が「あとで読む」タブを一旦しまえるので地味に便利です。

Generally OK. I would like to be able to sort them. I expected this to be under "Manage containers," but I don't see it there. Secondly, I also have a problem that quite frequently, I get a screen that says "Open this site in your assigned container?" When I click on the button to open in the assigned container, about 50% of the time, it simply doesn't do that. I have to go to the top and pick the right container and enter the address. It seems clear that it is built to confirm the opening of the right container and then go there, but it doesn't work when you want it to.

А как синхронизировать контейнера между компьютерами???

Useful feature for multiple gmail or any other logins on same window. Helps to keep privacy and stops facebook stealing cookies. Good one.

I need a button to open all tabs with one click like the session box in chrome
