This is exactly what I needed. Simple and intuitive. I have used session box as well and session box has some additional functionality. Still this beats everything.

Tremendously useful once you setup your usual containers.

Super. Sehr effizient. Danke!

It should be a part of Firefox by default not an extension! Just like Brave.

I needed a method to allow me to run multiple WhatsApp messaging shells from different accounts at the same time on my Desktop/Laptop computers. Firefox's Multi-Account Containers Extension allows me to do just that. Seems to work perfectly.

Can you add a function to export all the containers to an .html or .json file or other format so that you can import them into another computer's extension? This makes it possible to export and import data such as bookmarks.

Great extension, top for unblocking specific sites with custom proxy settings (instead of using global VPN). Bravo, Firefox, spread the word!

This add-on is what differentiates Mozilla Firefox from the rest.
