Almost good..
1. Container info does not use firefox sync
2. Reopen in a different container should have an option to delete all cookies in current container.
3. Have an option to ask for which container before opening a new domain.
4. Should be integrated to core firefox rather than addon.

Awesome addon

Great that this container feature is here. I would love to see it extended to something like tab groups, as a logical progress of my "Personal" and "Work" tabs beeing separated visually.
Keep going, thank you very much!

Works nice. Could be improved.

A nice feature would be i f you could set default container on which tabs open depending on the time of the day.

Example: open in "work" container from 9 to 15 hs.

A great ad-on to separate my shopping from my research or banking browsing. I sometimes forget to switch to the right profile - and it's (for obvious reasons) not possible to switch an open tab from one container to another. So the missing 5th star is more to do with my own discipline than with the add-on...

Works well, 5 stars i you can sync settings on multiple devices

I know it separates cookies into containers because my login for LastPass doesn't carry over. Points for provability. I only wish there were keyboard shortcuts to open containers in new tabs/windows.

it's great!
but when i us it. can't upload video to bilibili.com.
no problem on Youtube.

The idea is nice for added security and privacy. I would like to see options for only allowing or disallowing certain domains in the current container, managing container settings and data, such as cookies and clearing the data and allowing to move all tabs of the allowed domain to the current container.

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).

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.

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.

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

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.

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.

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.
