This extension is great and works like a charm, allows you to use different social media apps in different containers making it a little bit more difficult for them to track you, plus, allows you to check different email or whatsapp account in the same browser.

Not only useful for keeping separate logins and separating work/private browsing, it also is a very helpful tool when developing and testing web sites

Older versions worked flawlessly. Now, any time I click on a link of a page already opened in a container...it opens outside of any container. When I right-click the link and ask to open in a specific container it opens the link outside of any container. That makes this addon useless.

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.
