they changed it so that facebook automatically opens up in a designated facebook container & i can no longer use the addon to be logged into two facebook accounts. it seems there's no way to bypass this

Love the functionality- being able to separate different sites into different containers is a great security and privacy feature.

It works great!

Protip: you usually want to middle-click the new tab "+" button. Left-clicking it will use your default container. Middle-clicking it will open a new tab in the same container as your current tab.

Awesome!

It's great to have multiple cookie sessions so neatly integrated into the browser. One identity per color makes it easy to identify the container for each tab. Highly recommended.

Awesome!

very good

This extension offers all the same account separation benefits as chrome users, but in an even better package. You know only have to sign into your password manager once, you get one history, and one set of bookmarks.

For me this is perfect. All of my work, school and personal accounts can be separated into containers and I can also have a special container for each social network I use. This extension is so useful it should come pre-installed.

Would like to see implementation of temporary containers.

Need a way to have certain containers act as private tabs - IE it doesn't appear on your history.

This would be great if it could sync your containers across all computers. As far as I know this cannot be done. Thinking about not using because I have to setup on each and every computer separately. Everything needs to sync based on your log-in. Please fix.

Très utile pour améliorer la vie privé sur internet si on l'utilise ensemble avec des autres outils pour limiter la collecte des données privées.

Вроде, работает. Контекстная реклама в разных контейнерах не пересекается. По крайней мере, пока .

-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.
