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.

No sé cómo he podido vivir sin esto

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.

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.

Ottima idea, facile ed efficiente!
Una volta aggiunti i siti è del tutto automatico.
Bravi!

Nota per sviluppatori: non è immediato per un neofita aggiungere i siti nei contenitori..

Ever searched for something in amazon then saw it's advertisement in Facebook? No more!

If you choose opening FB in one container and amazon in different container then FB won't be able to track what you are doing on Amazon and therefore can't show you any related ads.
I also Isolate google products so that google also doesn't get to track me

I find it very usable for privacy!

Great work. Please allow us to open specific domains directly in the container.

decent containerization concept

Best tool for keeping all my tabs organized! Highly recommended!

Cumple su funcionamiento, dejas de ver publicidad de acuerdo a lo que navegas en otras webs.

Awesome! Thank you Mozilla!

Suggestions for improvements:
- sync across devices
- allow the order of containers in the list to be changed. "Ctrl + ." is already in my muscle memory. Now I want to have less times to press "arrow down" to reach the container I wanted.

Great extension, awesome for pages like facebook and reddit which track their users
