I'm using this addon to convert people (back) to Firefox, that's how useful it is.

THis is the BEST extension EVER!
It helps to isolate your actions (for example banking operation/shopping history/social networks profile/yor work tabs and pages/etc.
Now you don't need to have several profiles in browser/several browsers or open incognito window.
All that you need - is to open new tab in a separate container.

An excellent and wonderful addition to one's collection of cyber-security tools for safeguarding one's privacy. Highly recommended. Thank you, Moz://a!

This is one of THE BEST addon someone could ever need.
If you have more than one identity or email account you use in some site, you MUST install this addon.
You can have multiple tabs of the same site, using a different identity (account or email) in each tab.
All I can say is I DO RECOMMEND THIS ADDON...

Esta eh uma das melhores extensoes que alguem pode usar. Se voce tem mais de uma identidade ou conta de email que usa em varios sites DEVE instalar este addon.
Voce pode ter varias abas do mesmo site, com uma identidade (login ou email) diferente em cada uma delas.
Recomendo muito...

Prise en main rapide, intuitif, efficace, interface claire sans fioritures.

Only more icons are needed to distinguish my containers. Or atleast giving the option "to hide the icons"/"choose a blank icon" since I'm using emojis in the name of the containers.

Thank you for your work!

Awesome and useful add-on. More icons would make me give this 6 stars!

Amazing, this is a life saver for me.
PLEASE add the ability to sync containers settings with firefox sync
