Essential for many of my workflows. Works very well.

This is an amazing extension for me since I need to log into my Google corporate account and my personal Google account, and I can have both of them open in the same browser in work and personal containers. Also, having different containers helps me manage web logins and autofills much more easily.

Очень удобно! Все сайты теперь по категориям!

An absolute must if you login to various sites with different profiles.

[2021-Aug] A great and useful extension to have, but it's missing the ability to disassociate a website from *any* (or all) containers. A website's association can be moved from container to container, but cannot be reset back to no container -- something that would be needed in the case of SSOs: to log into the same website with different accounts (under different containers).

It's wonderful!

The add-on is great! I can imagine that it's a bit difficult to understand if you are not that much into computers though. The only thing that I can not find is a way to manage which tabs belong to which containers. You can assign them, but you cannot manage them.

If that "feature" is added, or some one of Mozilla can explain to me how I can manage it, I'll update this review to a 5-star.

EDIT: I've found it, but why is it so hidden?
It is hidden 6 clicks deep within the extension's toolbar button. Why not put that also in the settings of Firefox add-ons menu?

Simply awesome. Discret and efficient, you only notice this extension is installed when you needed, then you just use it.

Great extension - apart from the 'always open this in a container' feature. Easy to mistake the icon in the address bar for the main one to open a new tab - end up setting default containers and spending forever trying to work out how to remove them. Would be a five star review if this were fixed.

Incessantly asks if you want links open in current container or not. What a stupid and illogical behavior to program into an extension. Smarten up.
