Very practical! It's really easy to be able to separate various accounts and websites!

Great idea in principle. But it is extremely annoying that it deletes configured containers so often. Notably - it does this if you disable and re-enable the extension. With no warning! It's a cardinal rule not to delete user data without at least one layer of warning.

Needs work. 700 issues reported.
I just can't make it do what I want.

First it was great. Five stars, then suddenly I was greeted by literally all of my containers gone. Gone. What happened here? Edit: Turns out even all my logged in e-mails and accounts are logged out?!

ótima extensão

Has done what it's supposed to do so far. A caveat though: when I've set a site to open in a container, I can't revert that change to it to open without a container/in a default one.

I like this but its very glitchy.
Some sites have a bunch of redirects etc, and new tab/window creation, it doesn't create that window/tab in the same container, so I can't use it for some sites.
It needs an option to export/import a list of sites.
Or check existing container cookies and open based on those existing cookies.
This should also just just be a feature within firefox.

Multi-account containers is simply phenomenal. It helps with neatly segregating different portions of our internet exploits, a feature that at least I thoroughly enjoy and appreciate.

Very organized and serves me well

I like idea that Mozilla tries to move some of the power user functionalities into add-ons making the browser more lightweight by default.

But I really missed this feature, when it was removed and just found this add-on today.

Can't sign in using FB oauth on other sites when inside container
