This is a game changer extension for personal privacy. Preventing tracking from websites like Facebook and Google across other websites we visit. The only thing this extension is missing is a way to backup manually created containers and integration with Firefox Sync.

What a great idea to try and separate browsing tabs from prying sites!

I am really enjoying this container tabs add-on, it has a very useful functions such as separating accounts, defining a specific container to open specific websites, hiding an specific container...
The reasons I'm not going full 5 stars here are in my next paragraph babble, but it's still a REALLY GOOD add-on!
I'd love to see just few more features such as sorting container tabs in new windows and being able to "mute" or "offline" certain tabs without hiding them (and also the I could choose what tabs to un-hide and in which - or a new- window) much like how you used to be able to choose what to restore after a crash. Being able to open bookmarks on containers also, and setting up a default container... Also, being able to save settings with my firefox account for cross-device ease and consistency!

Really useful for web development

For me this is a must have. Such a great extension and the ability to make custom container categories is awesome. I only wish the containers/rules synced accross devices.

Would love it to have options in the context menu to open links in containers

A really clever, simple add-on that I'm surprised no one has ever thought of before. A lot more convenient than switching to a separate Private Window any time I don't want to be tracked.
Works especially well in combination with Mozilla's Facebook container extension too, to combat those pesky Facebook trackers.
If I have one complaint, it's that you can't directly enter a container tab by right clicking on a link from your bookmarks toolbar! You would have to do a Google search for it and then right click on the link, which kinda defeats the point of having bookmarks if I want to use Container with it. Please fix this Mozilla!
Otherwise, an excellent add-on.

Une excellente extension permettant d'utiliser pleinement la fonctionnalité de conteneurisation de Firefox. Pas de bugs à l'usage.

Effective at what it claims to do. Easy to use. Have had no issues with it.

I'm really enjoying containers. I do a lot of Cloud and internet work and previously was opening normal and Inprivate Edge, IE, Chrome and Firefox sessions to be able to log in to many systems to avoid the browsers caches clashing. Now I just use Firefox, it simplifies it no end.

Easy to apply. Looking forward to the enhanced security provided by the separate containers.

Too buggy to be usable for privacy. "always open in " shows checked, but domain isn't actually associated w container. No way to have links to non-associated domains open in default container. "open link in.. " doesn't work. No easy way to associate many domains to a container.

An amazing extension that allows one to manage websites in containers in ways that that weren't possible before.

One small improvement I would like would be some more advanced settings on the container profiles such as:
- specific urls to open in containers instead of domains
- be able to sync the container profiles I set to my Firefox account to be synced to all browsers with that account

The extensions loses out its settings after every Firefox update, ideally it should be synced with user's Firefox account. Except this all great !!

Very useful - I have multiple Google/Amazon/Sharepoint etc accounts for work/private/clients etc, and this lets me keep them nicely separated, without the notorious logging out/logging in to different accounts all the time!

Helps me a lot. I appreciate it

Utilidad indispendable. Firefox es el mejor navegador y lo vuelve a demostrar con funciones como ésta.

Aunque es posible que exista la función no la he encontrado: Sería muy bueno activar comandos del teclado para abrir pestañas y ventanas en distintos contenedores. Aunado a esto, me parecería excelente tener la opción de que no se compartan el historial y otros datos de navegación, de manera que sean efectivamente contenedores aislados, aunque esto podría asemejarse a la acción de abrir una instancia distinta del navegador (que no es precisamente lo más práctico), o de usar el modo privado, creo que puede ser muy útil la función.

Por último, gracias, Firefox.
