Another FF product that deserves 5 stars.

Login using different accounts on the same site is great. Cookie peace of mind is great.

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!

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!
