This need a better way to add sites to containers.

Very nice, BUT missing essentials: container preferences sync + container reordering. Moreover, mobile support + temporary containers could be a much desired addition.

So cool :)
This allows me to "box" all google websites in its own container and all Amazon websites in another.
Plus, I can have as many containers as I want, in case I want to log into something with different accounts at the same time.

The importance of a browser extension like this can not be overstated. The fact that Mozilla them self maintain it makes me feel warm inside. Much privacy very container!

Usability changes/default selected container type when opening the popup/shortcuts to open container

It's awesome, but why can't we change the order of the containers in the containers list? That UI feature should be a no-brainer...

best add-on ever created

Very useful. I'm using multiple accounts on for the same site and with this extension I don't have to deal with multiple browsers and incognito mode.

This is one of the most amazing feature of Firefox, at work we use the GSuite and Chrome with multiple accounts: this add-on allows me to ditch Chrome entirely.
I am also converting other colleagues to it, little by little.
I am an IT Technician at Salesforce :)

Works best when you create 1 container per website (twitter, youtube, etc) and set it to automatically open in the appropriate container.
