It would be ideal to be able to clean private data from containers. I love the option to clear browser data when closing it, but it would be very useful to be able to clean the containers in a particular way (or if there was one that was automatically cleaned when closing Firefox).

The only major thing that could be better, is having the tabs group together like in chrome.

Excellent for keeping accounts separate and from sites tracking you across the web. 2 small caveats: reordering containers doesn't seem to work under the "+" dropdown menu, and syncing to another FF instance doesn't migrate your custom containers. Not looking forward to setting up the additional 27 containers I use in each instance - and I use many...

Everything fine with this new feature like Multi-Account Containers but I can just add that I if you can do something with the history by container can help to no loose the different webpages that I visited, because the container just safe the current page where was my last visit, it doesn't show me the movements forward and behid that I made.

Hiding Containers don't work anymore

a bit finicky to set up

I use it primarily to have multiple Microsoft and Google accounts running in the same browser window. When used properly, it can also be a great privacy tool (to keep sites from knowing about each other).

An extremely powerful extension that allows you to have multiple accounts for the same service on Firefox. It's a great tool for separating your personal and professional life without having to use more than one browser. It's easy to set up, simple to use, and your containers sync across your Firefox account.

actually it's useless in cloud. i can't open spotify in container in any other device when it's saying there's cloud sync.
