That's an excellent idea, but it can be way better. First of all, it should be incorpored to the browser as a feature, including the mobile browser. Second, the settings should be sync on Firefox Account Sync. Another great feature would be the possibilitie of incorporate domains to a container (ex.: add just google.com instead of keep.google.com, calendar.google.com, etc etc). Please, Mozilla, keep working on it!

I love my wife I told her I did know anything and really I did not dumb by know means but she spent a whole teaching her self and it got to the point I could do nothing or see nothing I know something was wrong so I'm a mth and a half I taught my self and locked her she super pissed but I love you Mamas

Excellent idea, but i can't actually use it without analogue in mobile browser.

Almost perfect.

It would be great if we could, per container, delete cookies/cache/history.

It is a nice idea. Unfortunately it does NOT work. If I sign into gmail in my "Personal" container, the session extends to all other containers. If I open youtube in its own container, I'll be already logged in my Google account. If I log out, it'll log me out from all containers.

This is one of the greatest Firefox extensions. But the fact is has no way to sync between browsers/pc's or export/import settings, makes it completely worthless.

Almost perfect (already deserved the 5 stars) BUT it would be awesome if I could bundle each container individually with a start page. I use it mainly for testing purposes and clicking on the different containers opening my different test sites would be cool!

Marvelous extension to separate your day-to-day login data. I use it for web development and social media management.

I absolutely love this add-on. Instead of using multiple browsers to separate work and personal, I can now use tabs in the same browser. Designating containers for individual websites is also a great feature (looking at you, Facebook).

Assuming this add-on works the way it seems to I'm very impressed. The only issue I'm having is not being able to re-sort containers in the list.
