Revision 2:
Is it really necessary to require the history setting to be "Firefox will remember history"? Why not drop that requirement and use the container idea as part of individual tabs in Firefox? Allow a setting that will "containerize" each individual tab.

Revision 1:
Containers now work after turning setting options/privacy & security/ history to "Firefox will remember history." Review will remain at 1 star - now I have to manually handle history and cookies. I'm not sure containers are worth this inconvenience.

Original Review:
Completely non-functional, counter intuitive, worthless and useless. Total gibberrish for user instructions. NUTS!!!!!!! really wish I could use this - but ........ I'll just have to rely on closing and restarting Firefox after using some google product or facebook.

After watching a short video on setting up the Multi-Account Containers was up and running in no time. Pinned multi-account tabs open automatically when using Tab Session Manager. No problems whatsoever.

very good concept. simple execution. more features would be good.

Only learned about it shortly, have been using it for a few days and love it. I now use containers for pretty much everything, it's super useful and really simple to use.

I've just created separate container for social media, separate for financial sites, separate for searching for flight tickets, work, private things, etc. Can be logged into Gmail with work and private account on 2 separate tabs and none of the account will be aware of the second one. I have bigger control over what informations can be tracked

Module super utile pour bien compartimenter ses activités web et séparer les grands méchants loups du reste du troupeau. Attention que les compartiments ne communiquent évidemment pas, donc faire un compartiment Google et un Youtube rendra inopérante toute connexion au second. Il faudra regrouper dans ce cas sous le même conteneur les sites d'une même "famille".
Seul ajout en tête: pouvoir ranger les conteneurs, plus de choix d'icônes.

This is a great extension. Perfect for having separate tabs/sessions for personal/business work. And I love the flexibility of having all tabs in a single window, or separate. It was the last thing that kept me using the other well known browser, but now Firefox is my default again.

Seamless. Thank you.

Suggestion:

Currently:
When you open a link in "Tab 1 - Container A" that is set to open in Container B, the link opens in "Tab 2 - Container B).

Improvement(?):
I think it would be better if the link opened in "Tab A - Container B". Meaning that (Tab 1 - Container A) changes to (Tab 1 - Container B)

Second Suggestion: Fix to a bug? = sometimes when I open a link that opens in a new container, 2 tabs open instead of 1

I like the overall idea, but the performance is not good. Tabs are noticeably slower and jerky with this add-on enabled. I'm disabling it for now.

I would say Multi-Account Containers is a life saving plugin. In addition to many good advert blockers, this plugin isolates all of the activities of certain website(s) into a single box, and do not let them communicate with each other. Great Fox Team, Cheers!

Λύνει τα χέρια σε χρήστες όπως εγώ που χρησιμοποιούν πολλά profile. Τώρα πια δεν είναι απαραίτητο. Είναι εξαιρετικά λειτουργικό μια και εκτός από τον χρόνο που γλυτώνεις, τα έχεις όλα σε ένα παράθυρο.

It's nice to keep my major groups of websites separated from each other so I can't be tracked across them via cookies and local storage. Love it.

Multiple Account Container tabs is a break through extension that allows me to nicely compartmentalize my online presence between social, personal, banking, multiple work accounts, etc. Really straight forward and rock solid.

No sé cómo he podido vivir sin esto

Only reason I don't give it 5 stars is because It doesn't sync container settings between devices.

Questo add-on dovrebbe essere built-in firefox, non opzionale.
Risolve definitivamente due problemi enormi:
- il tracking tramite cookie sui network di siti per la profilazione degli utenti
- la separazione degli account casa/lavoro forniti dallo stesso provider di servizi

GRAZIE MOZILLA.

NIce add-on, but one thing I cannot seem to do is to pre-define websites to open in different containers so I don't have to choose container every time I load that website. Perhaps I have missed something.

Been here a few days and I like em. Super convenient (although sometimes I forget to use them; when I open a blank tab, I'm still in the habit of using the ol +). Makes me feel cool and slightly less under the microscope when I'm browsing. Recommend.

Excellent ! Il faudrait néanmoins que les paramètres communiquent via le compte Mozilla et que l'extension soit disponible sur Firefox Mobile.

Do 3 stelle per me stesso perchè ormai i preferiti me li sono gestiti a modo mio con cartelle e sotto cartelle e ben ordinato, però come votazione altrui darei un bel 4 è un idea molto carina per chi volesse salvare i propri preferiti e magari con uno pizzico di colore.
