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.

still using it snice it was an experiment. Can I download extensions for a single profile only? I dont want the installed extension snooping around other tabs

This has been something a long time needed. The biggest issue is in overall usability. The process of assigning a tab (especially one already open) needs to be streamlined. Still, it does exactly what it claims to do, and does it well.

Love using this to help keep some semblance of separation between different activities tracking you, especially facebook and amazon. Only thing missing is that it doesn't synchronize across browsers, so I have to re-create the containers and web sites on different machines.

Very useful! Though needs better control of settings and easier ways to open tabs in the desired container, switch containers for a tab, etc.. Clunky to add sites one at a time. And desperately needs more granularity: for example, I want Google Maps to open in a separate container than Google Search.
