So easy to use! Easy to keep common items together.

Nützlich für mehr Übersicht
Seit ich die Container habe, hilft mir die Farbkennung, den Überblick zu behalten. Das ist wirklich praktisch. Die Installation geht leicht von der Hand, die Nutzung ist fast selbsterklärend. Ich differenziere die Farben nach Anwendungsbereichen und Kunden. Ich hätte mir da mehr Farbauswahl gewünscht - auch deshalb nur vier Sterne, denn ideal wäre es, die CI-Farbe des Kunden verwenden zu können. Das klappt nicht immer. Kann ja noch kommen. Auch bei der Icon-Auswahl wäre etwas mehr Variabilität schön.
Extrem praktisch wird es, wenn man das erste Mal bestätigt hat, einenContainer öffnen zu wollen und das Häkchen bei "Merk dir das" gesetzt hat. Dann kommen keine lästigen Fragen mehr und Links werden im selben Container geöffnet.
Schnell erlernbar, großer Nutzen, wenn man ein visueller Mensch ist, unaufwendig im Handling - klasse.

You've already been hammered with the privacy benefits and yada yada.
So I'd like to outline another major benefit: being able to authenticate to the same service with two different set of credentials. (i.e. logging into the hosting provider with both my personal account and the company's)

At the time of writing this is not working with Sync and there is a lengthy discussion on Github about the challenges of that.
Why it would certainly be nice to synchronize it's still useful as it is.

I work as a web developer on the OutSystems platform and use FireFox all day long for testing, inspecting and debugging HTML, CSS and Javascript code. In my opinion is the best web browser out there :)
Until I knew the multi-account containers extension, I had to constantly login and logout while testing web apps under several profiles. Now, with this extension, I can be logged in under several usernames (each with its own session) on the same browser window and it has made my work soooo much easier!
Thank you very much for your fantastic work on this extension!!!

Indispensable dans un environnement multi-utilisateurs ou dans un contexte de test isolé.
Essential in a multi-users environment or in a isolated testing context.

Me parece una aplicación estupenda, al menos me da sensación de seguridad. Le quito una estrella porque tuve algunos problemas logeando en algunos sitios como Youtube, aunque parece que se han solucionado en esta versión.

Almost good..
1. Container info does not use firefox sync
2. Reopen in a different container should have an option to delete all cookies in current container.
3. Have an option to ask for which container before opening a new domain.
4. Should be integrated to core firefox rather than addon.

No hay nada más util, tiene la opción de filtrar sitios para que siempre se habran en un contenedor especifico y es lo mejor

With "Firefox Multi-Account Containers" , I can have multiple gmail accounts in different tabs at the same time. I found this to be very useful. Thanks to brilliant brains behind this!

Very useful, specially for the developers.

Works well. Allows me to open the same website with different identities which is really helpful at work. Thanks!

Awesome addon

Super easy to use, only two clicks to open another account.

Great that this container feature is here. I would love to see it extended to something like tab groups, as a logical progress of my "Personal" and "Work" tabs beeing separated visually.
Keep going, thank you very much!

Pretty cool! HELPS ME A LOT!

Gutes Addon um da Tracking ein bisschen einzuschränken.

einfach zu bedienen, funktioniert zuverlässig

Muy útil, la verdad fué la razón por la que migré a firefox a parte de su rendimiento

Great addon. But it needs a bunch of features. Like moving tabs to a container. Also, it's a bit resource-heavy.

Very useful.

3 features that would improve it a lot: a) move tab to container; b) open all future tabs in this window on container X; c) open all future tabs in container X until I say so

One of the best Firefox Add-ons, great for keeping data collecting/hoarding websites and services in check. I'm looking at you Facebook!
