This is much better than managing different profiles. This is more practical. Profiles have separate DB for stored passwords etc., which is annoying.

To make it easy to use, the Firefox team must work on easier short-cuts for container, container-tabs, default window for containers etc.

Great extension and exactly what I need. But I keep losing the containers and had to start over. Currently lost 25 containers (happened several times before but I got only few back then). I had about 50 accounts to manage and I'm about to make 50 containers as well. Now thinking that I may lose them again and will have to start over is very frustrating. I don't mind losing login state and have to re-login once in a while but losing the containers is very stressful. Please add backup and restore feature.

Very useful and simple to use. I think I like it better than Chrome's profile switching.

Finally, sync! 👏 Thank you very much!

A must have. I've switched all of my multi-profile activity from Chromium (not my preferred browser) to Firefox (my preferred and favorite browser) Multi-Account Containers, finding it much more useful, handy and, especially, resource efficient. Keep it up, Mozilla!

Simply exceptional. This add-on is the one that kept me using Firefox because it is very, very useful. I can have many "profiles" with which to log into the same websites using different accounts. It's super easy to use and works perfectly. The container settings menu (second screenshot) could take some polish, but overall it doesn't hinder the usability of the add-on.

My job as a freelance translator means I work for different clients who sometimes use the same services, i.e., I have more than one account with those services. Without Multi-Account Containers, my job would be a nightmare. Best add-on ever.

The idea is nice but unless this extension can sync all of your container settings to the Firefox account it's not worth the effort (I can do the same by creating a different profile), especially considering that it often forgets all your containers and you have to set them up from scratch (it's pretty frustrating).

Another missing feature is the ability to open bookmarks in a container quickly. There should be a context menu action for this, e.g. Right click a bookmark > Open in Container > Select a container.

Great extension, just needs syncing so we don't have to repeat setup on every device.

Pros: 5 stars because it does what it says it does and well.
Cons: No saving settings across devices.

Almost perfect extension for me. It let me separate accounts on sites or group sites...
After mess-up with certificates I lost all my custom made preferences and containers. Add back up ability even if I move to other computer and login to my Mozilla account I feel same good Firefox I'm used to.

Simple and useful application, but... It deleted all of my containers when I disabled it for short time.. so it should be? Then how to restore containers?
