Very helpful to my day to day use. Highly recommended.

Add-on works exactly as advertised. I can juggle different logins easily and simultaneously without having to swap back and forth, which is great for handling business and personal social media accounts.

Nice and inspiring tool to manage many accounts in social media platforms

Super pratique pour séparer comptes personnel et professionnel. Le seul problème est que lorsqu'on indique que tel site doit être par défaut ouvert dans tel conteneur, il devient impossible de l'ouvrir dans un autre conteneur.

Super handy to keep track of both personal and professional accounts. The only problem encountered so far is when having a website being open in a certain container by default, it becomes impossible to open it in another container.

Pretty much seamless. Keeps certain tech companies separate from the rest of my browsing habits and seems to keep ads from following me around the internet.

It's a must have and I think it should be part of Firefox by default

Very good and meets my expectations

so nice

The time spent setting up your sites and getting your head around the idea of containerized cookies is time well spent. This does exactly what it says on the tin, and it should be baked into the standard Firefox experience by default in my opinion.

Works like it says, and allows you to keep trackers confined to the websites they come from, as well as being useful for signing into multiple accounts on the same website at once.

Pretty damn good addon. I'd love if this came to Firefox Android too. Pretty please :)

Works great. A must have for any browser in this day and age to keep your identities separated and secure. Glad to see Mozilla pushing the envelope.

Only thing I think this is missing is the ability to create disposable containers, which is picked up by the Temporary Containers add-on.

My only drawback on this add-in, is why isn't it automatically a feature for every website? We need to put every domain or subdomain in its own sandbox, regardless -- people think this is already the case.

Does exactly what it should.
11/10 would use again.

Extremely useful add-on for managing privacy and multiple accounts.

so useful! good for privacy, separation of work and home contexts etc. Also, very handy for software dev where you need to test multiple roles and uses within a web app.

This works very well - excellent add-in.

This extension is proving essential to maintain privacy on the web. Thank you for your efforts, it's extremely valuable!
