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.

As the title said, this is by far the must have extension. Just a little bit uneasy to setup. But once set, everything will work like it should.

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

Worked as intended and quite smooth ( 2 weeks usage, as of now. No hang/slow down yet) but again syncing across devices should be a great plus

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.

too many acounts can get very confusing, hoping to get a few utilities or tools to make the organizing easier

As a software dev that has to open up sites in both admin mode and user mode, the multi-account containers has been great!

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!

I use this add-on mostly for the feature to pin certain sites to containers. I wish it would gain the features of Context Plus to move tabs between containers as well, but for now I use both.

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.
