the containers concept is amazing and gets better all the time. I'm self-employed and have numerous customers that their own set of accounts to the same services. Now, I can give each customer container, login to GitHub or Amazon with each of them and it just works.

Love this extension.. Keeps away the trackers and one can be organized also at the same time. Keep up the good work Team Mozilla...

Great Add-on

Awesome extension. It makes it much easier to log in to different accounts at the same time without interference, and keep websites from tracking each others.

really cool and helpful

Very nice but it is annoying to ask twice to remember the website assigned container by default. Why?

Great for privacy, great for multi-account access. Does what it says on the box.

To improve:
- Remove the "Open this site in your assigned container?" step, it's completely unnecessary. I've already said I want it, so do it.
- Allow (specific) extensions to work across containers, because I have to re-enter my LastPass password every time I open a new container, which is annoying.
- Ability to sync container config with Firefox account, for multi-device access.
- Ability to edit containers more efficiently, much like one would bookmarks. I'd like to be able to copy a folder of bookmarks and paste them into a container all at once.

Five stars if you save the containers and config for the site on firefox account and sync...
