Great extension. Good for keeping Facebook and Google from tracking everything.

However, if the extension is disabled and then re-enabled, for whatever reason, all containers are removed and reset to the default personal, work, banking, and shopping containers. This doesn't sync with anything and is beyond annoying. Containers are also not synced remotely either.

This is an excellent way to limit tracking data pollination across web services. You can use your cloud mail at home and at work simultaneously and without fiddling with profiles. You can shop in the Shopping container and not have the items you looked at populate the ads you see on other websites afterwards. You can run a casual news browsing session in a dedicated container and not let various websites you visit correlate too much about you, or the web giants that track your account's activity learn that you were really into that Taylor Swift story ;)

Awesome !

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.

Excellent Feature, don't knwo if its there, but would be great to have a default homepage for each container

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.

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!
