I absolutely love this feature of Firefox! It is one of the main reasons for me sticking with it. There are some things that can be improved, of course, but even as of now, it is a must-have in your list of useful add-ons

Works nicely, I'm enjoying this extension!

Does NOT work in private tabs!
I always use private tabs by default, once I installed the extension nothing happens.
I've checked the permissions and there's no way to allow it to work in private mode.

A real shame!

no longer auto opening tabs in the correct container that ive assigned them. not even facebook.

Works great and allows extensive customization. However, if you ever disable this add-on all of your custom configurations will DISAPPEAR WITHOUT WARNING. There is no apparent ability to save your container names and configuration. Although I saw no warnings on the add-on site or reviews, a subsequent online search revealed that this is a long-time known problem. User beware!

Excellent

the most convenient extension. I recommend it to everyone

Given all the privacy and tracking done by the likes of Facebook, Google and a host of others, using account specific containers along with privacy addons like CookieAutoDelete, Decentraleyes and Ubock, one can browse safely without cross site tracking or worrying about constantly re-logging into sites post cleaning of the full browser cache.

Muito bom! Consigo separar navegação de trabalho da minha navegação pessoal!

A very useful tool to keep your personal, professional, .... sessions from merging together.

I've been using this add-on for a while now and I'm a big fan. It has worked seamlessly to compartmentalize my activity and I'm pretty much at the point where I couldn't live online without it.

Did exactly what I needed it to do by keeping my accounts compartmentalized and helping to combat cross-site tracking. Great add-on and hope to see more good work from Mozilla in the future!
