This saves me a lot of time

Makes it really easy to manage multiple accounts from the same firefox instance/profile at the same time.

Quite comfortable to reach out your interest easier than ever before.

Has worked like a charm for me so far. Haven't crashed a single time in the months I've used it

1 firefox to open multiple email accounts

Muy práctico y útil.

Full disclosure: I miss Tab Groups! Like, REALLY miss them!

That being said, I've learned to live without them. Multi-Containers (from what I understand) may well supplant and/or replace Tab Groups some day, but until then the functionality it brings surpasses what Tab Groups originally did.

Placing websites in specific containers allows for multiple sessions within the same window, making it much easier to switch between multiple accounts without any complicated fiddling here, there, and everywhere; and as someone who maintains multiple e-mail accounts on the same service, it certainly beats logging in and out repeatedly! The additional benefit of reducing and/or negating online fingerprinting/profiling also adds to the usefulness of this add-on.

Highly recommend it, and hope its future is all but assured

RIP Tab Groups, until you get brought back from the dead :)

Je m'en sers principalement pour dissocier les réseaux sociaux du reste de ma navigation et cela fonctionne très bien. La procédure pour ajouter un site à un container n'est pas forcément toujours évidente mais heureusement ce n'est qu'à faire une fois.
Quelques fonctions qui pourraient être très utiles :
- Des containers exclusifs : les liens cliqués externes aux sites listés dans le container s'ouvrent dans le container par défaut.
- La possibilité "d'envoyer" un onglet dans un autre container.

Great add-on that has really helped me with the corp implementation of SSO cookies - one for prod, another for dev/stage environments - on top of the daily use to separate sites (banking from reddit, etc)

The only thing that is fundamental and that is missing now in Firefox is ability to show only one container at a time. Similar to Tab grouping that has been disfunctional from FF57. Power Tabs is nice add-on for newer versions but it's that's much bugged it can't be used.

Very handy and useful to log in with your different accounts (professional, social media etc...)

Does exactly what I need it to--keep logins for multiple "personas" using the same services separated. This is a huge time saver!

Simple et facile. Un must have !

Very useful for multiple logins and for keeping trackers under control and preventing them collecting your entire online world! Would be nice to have the option of syncing settings via Firefox Sync though if you wanted to use that.

Si vous tenez à votre vie privée c'est l'application idéale au quotidien.

It's a nice way to categorise my tabs without using multiple accounts. I just wish it could sync your settings across installs.
