Useful for keeping cookies separate. Would be nice to keep add-on's and their data separate too. For example, MetaMask should only be enabled in its own container.

This is a fantastic, must have, addon. Should ship with Firefox by default.
One thing that I'd like to see is being able to see the menu by right clicking the tab itself. It would solve the issue with some sites which disallow the right-click (e.g.: Google Drive)

Slightly disappointed. I hoped for different privacy settings for containers (like cookies policy at least). Now it just deletes all my cookies through all containers after closing my browser.
And would be nice to have the different addons set for each container.
I still need few browsers to solve this.

Awesome! 5-stars if I could easily take an existing tab and swap/copy/move/duplicate it into a different container (right now I have to copy URL, open new tab with different container, paste and go ... blech). Other people have asked, adding my vote!

Just add sync and open a new uncontained tab as a container and it will be close to perfection!

Every time I close and open the browser, tabs are reset to some state that was a couple of months ago. It does not restore the tabs and containers that were open when I closed the browser.

Fantastically helpful!

Would be nice to be able to move tabs over to a specific container and also be able to edit the list of domains in a container.

I have Samsung j16 (firefox 57.0.4) but says incompatible platform
But this page says it should be compatible
https://addons.mozilla.org/en-US/firefox/addon/multi-account-containers/versions

le veo futuro, pero deberia tener una opcion para abrir container por defectos y un atajo para abrir container en el grupo que deseas.

This is — quite honestly — the greatest thing that has happened on the internet since The Fappening.

Everything is fine. I use it everyday. Before firefox containers I was need to use chromium for job tasks, but nowadays I use only Firefox and split personal and job tasks in different containers. I am happy about that.
Many thanks to developers team.

I absolutely love containers! They help immensely with web development and having multiple test accounts. No more private windows and using both Chrome and Firefox just to test more than 2 accounts at a time!

This add-on is useful for memory management and organizing the endless collection of tabs I seem to keep open.

I look forward to how the developers can make these easier to use and organize. Certain aspects about the implementation feel clunky to me, but the need is real.

Excellent, maybe is a bit paranoid if you think of it, but works

5.0.1: the only lacking feature I can think of is one to move a group of opened tabs to a new window

Would be even more useful if settings (which site to open in which container) would be synced across the devices

Works great. Some irritations - no shortcut to open new tab in specific container. Can't specify the existing web site I'm on to go to a specific container - I have to open the tab container and then reopen the site in that container. Maybe I'm missing something? Would be 5 stars if I could do the above.

Best plugin in Firefox ever. That's why I still use Firefox for years.

Don't hesitate. Just download and use it now!

It worked great until all my add-ons got disabled. Because that got rid of all my profiles for this add-on.

It's a great way to keep cookies from different 'worlds' (i.e. work, personal, etc.) apart. Just works, and I've never had issues.

That said, not 5 stars for a few reasons:

1. URL autocomplete is shared between containers
2. Login (username) autocomplete appears to be shared between containers
