Absolutely invaluable

Very powerful & useful addon.

It's nice, but, can we have an option to open a site in 'no container' by default?

Realy good. Thanks for this add-on

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)

图标太少，不能准确表达容器的意义，比如游戏、音乐、编程、阅读等。

Too few icons to accurately express the meaning of the container, such as games, music, programming, reading, etc.

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.

It can be a little clunky to get all set up, but I like not letting Facebook spy on all my other internet use, and it's helpful to be able to sign into my personal and work Microsoft accounts simultaneously
