Nice, no other browser has this feature. And it made my life easy.
Thanks Firefox.

Long story short: I can't understand how I've managed to live before learning about this plugin.

This is a very good add-in, which lets me use Firefox for all my browsing and separating different uses from each other.
Previously I was using Ms Edge for work, but I don't need a separate browser anymore. And considering Ms is moving to Chromium, this is a very good time to switch totally to Firefox, if we want a free Internet.
It's also playing well with Facebook Containers. It just added another container for Facebook, without any effort on my side.

Привет. Спасибо за отличный модуль. Он помогает мне в работе. Единственное что, не хватает поиска по контейнерам. Их становиться слишком много. Сделайте пожалуйста поиск, мы после этого снимем видео, которое поможет другим людям выполнять такую же работу как и мы, и обеспечит установку Вашего дополнения в больших объемах. - - - Hi. Thanks for the great module. He helps me in my work. The only thing is that there is no search for containers. There are too many of them. Please do a search, we will then shoot a video that will help other people do the same work as we do, and will provide the installation of your supplement in large volumes.

Amazing. Superpower for desktop browsing. Would love it on the phones too.
