I can log in at multiple accounts for the same site using different Containers (no more incognito back and forth!).

This module saved my life for multi-sessioning in application in the same browser !!

Brilliant add-on, finally no constant browser switching for websites on which one has multiple accounts. The colouring of the tabs in container colour makes it easy to see at a glance to which container a tab belongs. Great job, Mozilla, I love this add-on.

Containers allows me to remain logged into personal and business Twitter accounts open in separate tabs at same time which saves time.

Great one, I like how I can customize name & color of containers, I like to use custom icon too, great job Mozilla, keep it up!

Easy to use, awesome to be able to separate individual accounts with only one browser open.

Very useful, it allows loggin on differents accounts to the same service (ex: two gmail accounts). It helps limiting the tracking and is easy to understand with the default categories.

This seems like a nice tool. I can't really tell if it's working as described and keeping cookies and tracking contained within different work flows. It's hard to know exactly. But the tool works well, and it seems that account logins are isolated withing a container.

A great tool for dealing with multiple web accounts. They finally added sync, which means this is now feature complete! Awesome! Please don't ever drop support for this!

Its very useful. Thank you so much.

This has great potential! Sadly it outright refuses to work in private browsing mode. I wish it also had a few more customization options too. Works perfectly on normal windows!
