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.

Nice add-on, it should be a default feature in Firefox, however there are some points that I think it can make this add-on even better:

- the option to keep my containers parameters after disabling/enabling the add-on. Actually, if I disable this add-on, I will lose all my containers and it will return to the default configuration, so I have to repeat all the actions I did before (renaming containers, associating accounts, etc..). I don't know if we can consider this as bug.

- History panel remember with which container a site was opened and reopen it in that container Or make different history for every container and even better, make it possible to choose to open container with other profile (I don't know if this feature is even possible :-) ).

- An option for sorting history by containers.

- A password protection for containers.

Keeping my most used tabs in focused clusters keeps my surfing fluid and convenient.

Please continue developing

easily manage session with category and tab
tab sorting supported

Very easy to use and reliable. I pack different containers with over 100 new tabs per week. No issues so far and no signs of leakage of information between tabs.

Couldn´t live without it.

A must-have add-on for Firefox. Nice job devs!

works great.

The feature of always opening a site in particular containers is a must for anyone uses container.

Awesome extension. It allows me to keep my personal and work sessions for emails and other stuff isolated in the same browser process. Great work team!

I really enjoy having certain websites open up in specific containers all the time (social, banking, news, etc..). It takes some time initially to get the bulk of your most frequented sites setup. But once you do, it's rocking.

Cool extension for accounts segregation. But lacks following:
- open URL in previously selected container without asking if I selected "Always open in ";
- open URL containing subdomain in container if I configured that container for main domain (example: shop.com, hardware.shop.com).

The only features I would like to see in this add-on to give it 5 stars:
- the ability to re-open tab in a specified container
- the option to have the sessions associated with add-ons be global or have the sessions be different for each container

The always open this site using a container feature is very helpful. If only there's an easier way to open the current page in another container instead of having to open a new container tab and copy paste the url.

That exclusive Facebook Tab helps you maintain your privacy.

Very useful for work computers.

Ótima extensão! Fácil de usar e muito útil para separar a navegação em determinadas tarefas

I love, love, love containers. Even when a site I need multiple accounts for has its own multi-account management, containers is better... and most sites don't.

It's perfect for separating out multiple accounts for testing a site during development; it's perfect for separating tabs out by category, each with a color stripe to remind me what they're for. It's basically perfect -- add in a self-destructing private container, maybe, and custom icon support, and I'd say it *was* perfect... but using colors with the simple dot icon is almost as good anyway.

Thanks, Mozilla. :) Containers are awesome.

Works great for me. I now can separate my work Gmail to my personal Gmail on different tabs without linking my Google accounts.
