-Need to be able to re-order container categories.
-Need to be able to remove categories and have them actually be removed (I've removed FB a few times but it keeps coming back (like the bad penny it is)).
-Need to be able to click on a non-container tab and assign it to a container easily.
Other than that it works pretty well.

This extension is perfect, I think it is a great security and privacy feature.
I have enabled it in all my Firefoxes

This is a great feature. The ability to maintain simultaneous sessions with multiple accounts on the same site is good enough - the privacy features are icing on the cake.

Makes browsing even more more secure by separating your bank accounts infos, from your Facebook infos, from the rest. Much better than the "private" browsing concept because the cookies for each of these world remain after each browsing session, so you don't have to start over again each time. Much better also, because switching between each container is automatic (if desired), so you don't have to remember who goes where : in itself this is a great security feature. Of course, as the name implies, if you have many accounts for a given site, it also allows you to stay logged-in as these various accounts all at the same time, which is great. Loses a star because setup is not smooth, but once everything is set-up, Firefox Multi-Account Containers becomes totally transparent and a joy to use.

Very fast browser with great security settings for using the Internet. I very much like being able to use containers to protect my identity by separating social media from shopping and online banking.

I have add and removed both Multi-Account Containers and Facebook Container several times. Neither seems to function or work with the particular FireFox set-up that I am using (FlagFox, No-Script, Colorful Tabs, Google Translate, WX Download Status Bar). I have reviewed several videos and none of the features function except for creating new containers (neither right or left click within the MAC drop down or the "+").

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
