It saves sessions and cookies into separated groups which is... kinda late actually. There's been many other extensions which does the same job with many more features as well, eg: open multiple tab groups at once, online sync (even across different browsers), group-in-group tabs and more. But since this extension is built specifically for Firefox, in terms of performance it performs better (sessions opened faster, less bug in saving cookies or such).

Really good feature. You can separate business and personal stuff, and different identities, and works very well. Essential and fast interface. Nice job!

the more privacy the better <3

Love it!
Would be cool if we could open more than 4 containers.

this makes my job soooo much easier... just need the custom containers to sync

Depois de escolher os separadores que queremos abrir de forma segura (banco online, Finanças, páginas de downloads, etc.) o Multi-Account Containers passa a funcionar de forma automática sem dar trabalho algum. É preciso apenas, da segunda vez que se abre uma página que escolhemos abrir dentro de um contentor, marcar o quadradinho a dizer que queremos abrir sempre num separador privado. A partir daí é automático. Nada mais simples e prático! A única coisa que acho que não funciona tão bem é quando estamos num determinado contentor, se clicamos num link sem contentor, ele abre no mesmo em que estamos.

The privacy extension I've been looking for a long time.
Nice job !

Meu uso dos Containers tem sido muito bom pois trabalho com várias empresas e separar as sessões de login é muito bom e prático ainda mais por poder colorizar as abas, sei de cara do que se trata.

Para que nunca usou, teste. Se seu uso do navegador é simples não perca nem tempo testando.

Helpful extension with nice idea:)
But, I would really prefer if I can mark my existing tabs with colors, not only creating new ones.

não uso muito

Exelente!

Of course, it's the best
but it is not compatible with the official Pinterest add-on "Pinterest Save Button"
// Please add the possibility to organize containers (change the order in the list)

Très utile afin de bien séparer personnel et professionnel. Utilisation aisée.

A perfect solution to get the best of both worlds:
- convenience of staying logged in on your sites, even between browser session
- privacy in the sense that cookie information doesn't spoil between containers

It is a good solution for a common problem. However, it is better solved in Chrome I think. At least it would be nice to know more in detail how it impacts syncing.

Containers was a much needed feature. It's a very powerful tool, although it's missing some functionality in it's current state, it allows for the isolation of different domains or websites. It's a bit cumbersome to use due to lack of usability, but that might be due to being a new feature. As of the time of this review (2018-08-18), I would like to see: Better container administration options, drag and drop sort order for example, custom icons, rgb color choice, a panel (bookmark like) where you can see the relation between the containers and the domains associated with them, custom hotkeys to open a specific container. All in all, it's a very nice and useful first implementation for the feature.
