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

It's almost a 5 start review. I would appreciate a streamlined way of opening new tabs in a container. And maybe, if at all possible, having a setting that would allow to open links coming from certain apps in specific containers would take this extension to the next level.
Otherwise it's a great tool to keep my multiple work account that depend on gsuite login apart from one another and (for the most part) always logged in inside a particular container.
