This tool is really helpful, as it helps me use different accounts for different services, without having to login and logout of accounts

As part of my work, I am regularly logging in and out of the same site with different usernames. Because each container holds its cookies separately, I'm able to run multiple instances of the site, which cuts back on my login/logout time and drastically improves my efficiency.

Firefox user for life because of this add-on.

I think there are a couple of additional features that could be added going forward, like default container and switch to container. But so far its brilliant and I get alot of use out of it, between personal and work accounts

very nice extension: it allows to easily manage multiple accounts (I use this to separate my work and home stuff)

Excelente, permite separar cookies y almacenamiento manteniendo una experiencia unificada de navegador e historial.

oui

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
