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.

Incredibly useful! It turns Firefox into 10 browsers in one, learning your preferences so each aspect of your life stays organized and separate!

Amazing. No need for different windows, different sessions are tied to specific tabs with color-coding. Much better solution than in chromium where you need a whole window

Lifesaver for some usecases. like mine :)

Absolutely irreplaceable and mandatory for me
