If you have multiple on-line identities or personas and you would like to ensure that there is no cross-contamination of personal information between them, then this is the extension you need. Likewise, if you want to ensure that Microsoft knows nothing about your preference for Mozilla products and services. Same goes for any other organisation, such as Google or Amazon, that likes to collect and analyse your on-line activities. You can define individual containers to keep your activities with each organization isolated and encapsulated, completely separating them from each other. What's not to like?

Vite indispensable une fois qu'on a pris l'habitude de l'utiliser. Evite de devoir jongler entre des pages en navigation privée et/ou plusieurs navigateurs.

Sure, the real under-the-covers reason this extension is great is the privacy wins you get by using it, but even if you didn't care about that (you should), the ability to quickly sort tabs by context and split out windows should be enough to win you over.

Makes containerization of work, social networks, shopping activities and whatever else comes to mind trivial. Prevent tracking of your social identities on shopping websites, and makes federated identities a lot easier to manage.

Really helpful if you you are using more than 2 G accounts daily

The add-on is awesome, but I would like that this one could be sync, because I have different computers and browsers where I work and at home I have to set up in every new computer.

Ok

I love being able to separate various accounts even of the same platform without needing open multiple browsers.

It does what it's supposed to

Great extension!

Works as expected! :D

This feature made Firefox an absolutely irreplaceable piece of software for me.
I'm ready to ditch all other web browsers, if only Firefox had better touch support.

Love it. It can take a little while to get used to, but the privacy gains are worth it.

Yes, great addon. But tell me, why isn't it integrated? Why are the containers integrated, but without the option to 'always open this domain in that container'? Where's the logic in that? Why do we have to cope with having two locations of where to configure the containers? Great addon, as I said, but integrate it 100% into Firefox already. I'm sure you (as in mozilla) have lost a bunch of users of containers already because they think "Hey, that's a pretty great idea, but a somewhat unfinished implementation."

Funciona perfeitamente.

Fantastic!
