Highly recommend getting this extension. This has done wonders for improving my productivity. It's great being logged into multiple accounts for one site at the same time.

Очень удобное дополнение. Все продумано.

I am missing two features: Default containers for new tabs and creating new tab by ctrl+t in same container as actually active tab.

Great! The only missing thing is support for Firefox on Android.

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...

Would be nice to be able to sort the containers or re-arrange them, also sync.

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