Very good extension (previously didn't know this was possible 😀). It's useful for isolating Work and personal tabs of course (eg. Github for work and personal account). Also proved to be very useful for opening AWS Console pages of multiple accounts at once (each in its own container)

Quirky and a smidge non-intuitive, but this add-on is incredible. The functionality of this add-on combined with OneTab makes Firefox insanely useful for the poweruser. More people need to know about this add-on.

What do I do with it? I have my Gmail accounts each open in their own protected named island. All of my google-verses live separately: day job, my two small businesses, an association I volunteer for, and personal. Beyond Google, I have 10+ other containers for Development work, Writing, Finances, anything Government and tax related, Shopping, Social Media, etc. And none of them can talk to each other.

This add-on is awesome. And with OneTab I can change context for what I am working on at any given moment, snapping in and out of whole suites of tabs.

This is powerful stuff.

Great extension. I love how i can keep cookies into different containers. I also enjoy the color coded tabs at the top. Makes it easy to see what is a business or personal tab. Great job!

The Firefox Multi-Account Containers is a fantastic extension!
It allows me to have several tabs open without the cookies & trackers screwing up my ability to go from various email accounts and pages to others, without having to log out and log in multiple times.
I use it every day and absolutely love it!

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.
