This is one of my most used and most needed Extensions. So useful to login into the same site using two or more accounts. If you pin the tab and allow cookies for the site to be stored you have your app - like teams in two tenants or outlook with different accounts - right there at your fingertips when you open Firefox. Must have for web developers that need to login into frontend and backend at the same time.

Saves the need for having multiple profiles so it is convenient

This is my most used and favorite extension with for Firefox. A no brainer at work where I have to manage different Microsoft accounts with their multiple services.

La verdad me encanto, solo es cosa de acostumbrarte y por lo menos en mac va volando, me gusta mas que safari

Fantastico, quello che cercavo! Grandissima idea e realizzazione super efficace!

A great tool to stay logged in on LinkedIn without sharing cookies to other sites.
NB: Searching google in such a container is not what one might want. It means you visit the results in the same container - so google will follow you.

L'unica estensione che funziona bene come multi profilo social, l'ho dovuta usare con la versione 135 perchè con gli ultimi aggiornamenti si freezava sempre il gioco di facebook

The best way to keep work and personal tabs seperate. You don't have to bother with swapping accounts, just open a container and your login info is saved!
