This add-on is an absolute must-have! I honestly can't imagine using a browser that doesn't have this functionality. I'd be lost without it - no kidding! Thanks Devs for making this, it's a killer feature. I'm not sure how this isn't a standard feature in FF and all other browsers.

I was using multiple browser to separate work and home use, having dedicated accounts of the same site in different browsers. With this, I can have the convenience of cookies so websites remember their last state and the separation of task types I want. Plus, The colour-coding is a quick and subtle way to destiguish the different uses/accounts.

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!

no sirve para multiples (distinats) cuentas, estilo multifox

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.
