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!!!

great i have multiple login in one site. Can open different container and login without leaving the browser

containers are the business!

Just starting to use but very interested in the concept and I can see a definite need for this. I am one who hates to close Tabs because I am afraid I will not be able to find it later on. I like Pocket but hate that I loose all contents if I loose my password and it has to be redeveloped. Wish there was a way to save the Pocket contents permanently or semi permanently for this reason a checkbox option would be good for choosing to save the contents this way. Nothing like being off topic and for that I do NOT apologize :-/..

Keep up the good work please.

It's a nice step toward having different personality/user profiles for the same installation of Firefox.

Love it! What I'd like to see:
- ability to sync containers (with open tabs) across devices
- or: add container info to synced tabs if possible, which would accomplish the same as above
- ability to choose which container to use when clicking the "+" button in the tab-bar

Works very well. Can be fiddly opening sites into new containers but can be set up to work smoothly and automatically once you do so.

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.

Simply great! Using it every day, helps me manage multiple accounts easily

Works great. A regex url pattern match for containers would be nice.
