Great feature, should be standard in Firefox! Keep up the great Privacy and Security focused add-on's Mozilla! Be sure to pair this with the Facebook container add-on for best effect.

very useful to keep goolge account in a container and use google search in another container

This is a great app and to make your experience even better, try using it with the Containers Helper add-on to manage your tabs more easily!

Works really well, I have yet to have any issues with it. I like the organization of it. Sometimes when I am doing research I have more tabs up than what should be legally allowed and the color-coding of this extension helps me keep things organized.

WOW!
The best browser in my life!
Many new features here and mobile app too!
Really! I'm really impressed with quality of the app!
You must use this app! Many new features and containers here!
I will use it forever!
Thanks

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!
