Beautiful and irreplacible tool for work!

very verrrrrrrrry good

i love it

LOVE!! needed this and I tell everyone I know about it!!

Great work team!!!

Brilliant add-on, a must for multi-tenancy cloud admins.

It takes a little geeting used to but the add on makes it really easy to isolate specific accounts. For example I open all the google websites in a google container :) And there's another add on specifically for Facebook :)

Fantastic desktop application. I would love to see it made avaiable for Firefox on mobile.

This plugin makes my life so much easier toggling between my many projects. Just wish firefox comes up with a way where we can sync the containers with our FF profile. Great Job FF Team!

One of the best extensions, one more reason to stick with FireFox!

Works flawlessly - I love it!
Prevents Facebook and Google from tracking everything.

I like this add-on! I use it for multiple Google and YouTube accounts and it works well! That's so convenient! Good integration e.g. it can open tabs in a container from the top sites page and from the Firefox - File menu. It would be nice to have an option to access the Containers' menu via right clicking on an opened tab (for accounts to be switched automatically if it's technically possible). Or even via page context menu. Also hotkeys would be very handy for some users. Anyway, many thanks to the developers for this very useful add-on.

Works pretty fine.

Great extension. I love it! I can parallel sessions of web whatsapp, gmail, dropbox. Thanks!!!

containers are the business!

I love this extension - I use it to manage multiple accounts in the same window. It's especially useful with multiple Office 365 e-mail accounts.

A couple of features that would be super helpful would be that it would sync to your FF account across all devices and a right-click 'Send Tab to Container ->' on the current page.
