I love this for separating my work, personal, and volunteer on-line activities. I don't want cookies shared across the 3. This lets me use a specific, unique identity for work, personal, and volunteer - without opening different browsers or changing logins every time. Before I was using Nightly, Beta, and Release with different profiles to keep them separate.

I'm really thankful for this add-on. It's great knowing it comes from people I can trust and the peace of mind it brings is priceless.

The only con I've noticed is that I had to reset Firefox recently and I lost all my Container tabs and had to recreate them. I'm still giving it 5 stars because that's a small price to pay.

Thanks Mozilla and the Multi-Account Containers Teams!

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.

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.
