pretty useful

Using this is way better than using different browsers to keep your sessions separate. A must have for anyone who has to juggle between different accounts for a given web site or web app.

Suggestion: When we bookmark something that's in a container, it would be nice to get asked if we want the bookmarked URL to always be opened in a the same container. This way we don't have to always think of manually putting it in one.

Easy to get started, provides different containers by default but can be adjusted to personal needs.
The different containers allow to log in to the same webpage with different user-accounts.

Super cool add-on. Helps keep me organized.

This feature is THE reason I've switched back to Firefox after many years on Google Chrome. Extensions that leverage this feature to give you additional privacy (Google and Facebook isolation) is great. I even use an extension at work to open a new container and log me into multiple accounts without having to log out first.

I really hope this feature gets implemented in other browsers because it's as revolutionary as tabs or private browsing mode.

Installed it in order to keep two Google accounts open and ended up finding more and more uses for it. Incredibly easy to create new containers and manage multiple accounts.

Super useful!

I personally like Firefox and this was the one feature it was missing for me to use it. After using it for a bit it was incredibly annoying to NOT have the current container open when I use Ctrl+T to open a new tab. Every time I open a new tab instead of it being a one step process It's a five step process. This makes me think that this program wasn't tested by anyone or was coded by monkeys. It's not even an option that can be changed or modified within the settings. I really want to use Firefox but until they change this I have to continue to use Chrome.

I love this plug in. I use to open a local app in Firefox and then in IE so I would have different sessions. I also used Private browsing to do the same but it didn't keep cookies and settings from session to session. I use containers to contain those companies that have a network of different sites. For example a company like "MyBook" that also has a messaging site called "Mymessager" I can put both of those in one container, that way "MyBook" is not getting info from my web browsing, or purchasing habits.

This is an absolutely brilliant extension that might take a little bit of getting used to, but can be a real timesaver. Aside from keeping personal, work, banking and other things separate, it's perfect if you need to access multiple accounts on the same site, and without losing session data in private windows when they're closed.

Very handy plugin

Really useful addon, allows to have several sessions for one site/service.

Excellent!

Required for how the net works today. Keep all the "big" sites in containers and unable to communicate with eachother.

滿不錯的分類容器！

Instalé los containers de Firefox y es como tener varios browsers abiertos que es algo que hacía antes. Por ejemplo, tenía Safari sólo para GMail y Chrome lo usaba para el SAT. Eso lo hacía porque GMail te rastrea todo lo que buscas en Google y no quería que me rastreara todo en Firefox y el SAT te obliga a cerrar el browser para salir de la sesión entonces ahora sólo cierro el container. Lo mismo Whatsapp Web lo tengo en otro container
