It works pretty well, but the "Always open this tab in new container" is glitchy
One of my tabs just wont open right now. And it's very annoying when I need to open in another container and there's nothing in settings where I can either remove that property or change it.
So I would advise steering clear of that feature.

A little bit of learning and set-up is well worth it in the long run. Yeah there is some ongoing care required to place web sites into the appropriate container but all in all time will spend.

I've given up on this.
There are some great ideas, but the usability is abysmal, development has been basically non-existant for years.

- The extension constantly asks you which container to use even when its the first time you've gone to a website in a specific container or even when you specifically ask it to use a certain container.
- Its also incredibly annoying to try and use the same domain in two containers, in contrast to what the addon claims, because the extensions keeps panicking about which to open and tends to override your current container choice at will.
- Its impossible to migrate your addon config to another profile or device, only the container names can be backed up.

I've used it for years and have found it to be more trouble than its worth. Rather than having a simple all-in-one profile swapper it is more akin to just colored tabs that break websites, make it impossible to use the same domain in multiple containers without hassle and doesn't respect your explicit choice of container half the time.

This application is fantastic ! I recommend it to anyone who enjoys Firefox as much as I do <3

Great addon and idea, but the sync is a complete sh*t show. When deleting containers, they just somehow reappear, and if likely you'll end up with TWO, since it seems to restore the one you deleted and then pull one from the sync. In short, the Sync feature is completely useless, and have left me with at least 5 duplicates of every container I tried to delete. Can you PLEASE fix this? And there's no way to purge what's stored on the cloud.

Best Addon. Can be a builtin in latest firefox browser.

Amazing feature! Allows a way more convenient way of managing different accounts from the same website and, at the same time, it is great that is an optional extra feature from the Mozilla Team. Recommended.

Helps me to login to multiple aws account without opening private window or another browser

Killer feature! The reason of my switch from other browsers.

convenient add

That's why I was looking for years. Thanks Firefox.
