Addon So great!

Very useful

Good for containing tracking sites, as well as for logging in with multiple accounts on the same domain within separate tabs of the same browser window.

This helps incredibly with keeping my work and personal accounts separate so I don't have to sign in and out constantly or use different browsers.

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.

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 .

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.

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.

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?
