Very handy and easy to use.

This is just an example why Firefox rules.
The slight issue that doesn't make the experience perfect is that if I have google.com on a container and search something, if I click on any of the results, this will open to a new tab.
Like there is no option of dynamically changing the container of the tab.
I would really appreciate this kind of function. And I am sure, a lot of people would appreciate the default experience of clicking on a search engine result.

Buona estensione per tenere i lupi fuori dai recinti.
Very, very good!!!

GREAT ADD-ON AND GREAT CONTAINER RESOURCE!!!
THANKS MOZILLA!!!

I use it every day, I cannot surf without this extension anymore!

.

So far so good. Nicely done Mozillians :-)

I have tried this addon on two of my laptops. Both systems stops responding shortly after installing and remains in hung state for around 20 minutes, then firefox crashes and system comes back to life.
using ubuntu 20.04.
Edit - Now that i have deleted add-on. it is still showing container option in right-click menu!

Одно из самых полезнейших дополнений. Очень удобно для использования одних и тех же сайтов из одного окна.

Cette extension est un compromis parfait entre la sécurité absolue (1 onglet=1 session) et la performance (n onglets = 1 session). Je sépare ainsi mes onglets par groupes: "Personnel", "Professionnel", "Finance", "Transactions", "Google", "Facebook" et "Suspect". Cela me permet, par exemple, de rester connecté à mon compte Google sans rouvrir automatiquement la connexion à chaque redémarrage. Un module indispensable pour moi!
