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.

Containers are amazing and have removed the need for me to use profiles as I did in Chrome now that I've switched to Firefox.

Two improvements are needed:
* [p0] BUG: when restoring (unhiding) tabs in a container into a new window, I get duplicates of all tabs. If I restore the container tabs into an existing window this bug does not happen.
* [p1] There should be a way to send all open (or subset) of tabs to a container
* [p1] I would prefer the default action for a new tab to be the last tabs container (without needing the ctrl+). Alternatively I would love to have a window be marked as a container and have all new tabs in that window associated with the current container by default.
* [p2] I want container sync to FF Android :D !!!
* [p2] Another nice to have would be to have different extension settings or even enable/disable extension settings per container.

This is truly one of the most important extensions in the repository, with firefox developing in leaps and bounds, i truly wish this extension becomes a part of firefox by default as a feature in the future releases. Love it!

Must have add-on! I use it to log into different AWS accounts.

This is awesome! Multiple office accounts and this makes it a breeze switching between the lot of em.

I've been using this plugin for a couple months and have really enjoyed it! I love the ability to have accounts, cookies, etc. separate but still in the same window. This plugin brings the last remaining feature that I've been missing from Chrome (simple profiles) to Firefox.

Good for keeping multiple accounts. Missing a feature to re-arrange the containers you create in the menu. Container names should also have the ability to sync between systems.

Idéal pour garder une séparation entre vie personnelle et vie professionnelle

good

Perfect!

Well done, and very stable. It definitely makes it possible to 'silo' my on-line lives … in a good way.

Ótima extensão, realmente muito útil.
Principalmente para quem precisa navegar com contas diferentes de um mesmo serviço ao mesmo tempo e não percebi aumento de consumo de memória.
O único porém é que os containers não sincronizam entre os dispositivos, mesmo usando o Sync, por isso 4 estrelas.
Ajustando isso estará perfeito.
Parabéns aos desenvolvedores.
