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!

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.

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 :)
