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.

finally..some privacy at last! get the containers addon Now! Multi-containers that is so that you can keep apart not only Facebook but all other websites you visit.

Very convenient as a way to have multiple logins to the same site within firefox

Wonderful tool for isolating work that needs conflicting logins on the same websites. Now I don't need to open a private window and relogin just to manage a backend. Also a great aid to segment your Google profile, I hate when YouTube recommends DBZA videos at work.

Needs a way to manually arrange containers, though.

Using containers is like having unlimited private sessions in the same window. No need to open a private browsing window or use multiple browsers just to open the same app with different credentials or sessions. Containers are easily differentiable by color code. 5/5 would contain multiple accounts again.

I love this add-on and use it all the time.

The only thing I would like to see is keyboard shortcuts for opening a new container tab.

Or at least, if I press the shortcut for a new tab, for it to open a new tab in the current container instead of in the default one.
