This add-on keeps getting better. One option I miss though, is to "leave" a container.
Example: I have all Google sites opening in a "Google container", but when I click on a search result, say the Apple website, I want that site NOT to open in the Google container. Same for external Facebook links.
This works if the new site has its own container assigned, but obviously that's not the case for all Google search results.

So if I follow a link while surfing in a container that's not assigned to the same container, I'd like to go back to "no container" or a designated "other sites container".

This could be an option per container or a global option.

very good

It doesn't remember your login details and you need to log in every time

Amazing Firefox plugin!
Should be integrated into Firefox by default(but as default being disabled), but either it's very nice! Recommend it to everyone & the best feature of it is: "Auto open this-website in a set-container", but anyway all of it's functionality is really nice and simple & I love it!
Reminds me of 'Docker's Containers' haha, but they're very different although their meaning is kind of similar :)

Love the ideal of "containing" entities who are trying to expand the perpetuate the legality and, perhaps worse, the public acceptability, of hoovering up and analyzing every single thing that I do on the Internet. If you think for a nanosecond that they wouldn't harvest every single bit of data about us that they can legally harvest, clear your head. And harvest means use. And use is just one fairly short fall to horrible abuse that will be very hard to recover from, if that's even possible. So contain them? Of course, please expand on this capability in the name of the public.

beautiful add on but have lack of icons hope you add more icons

I breaks Distrokid's claim YTube artist page, and works weird with Google, it constantly ask if I want open something in other tab which is annoying.

Very very useful! Miss some features like "move all tabs from one category to one window" or "close all tabs from category abc" ...

For this i need to use other additional addons not from Mozilla. And so here comes my negative critic:
Why needs this addon (and all other container addons) access to "all website data" and so also access to entered passwords?!

Very well integrated in the browser 👌

Genius add-on. So much better than the Chrome version with "People". With Multi-Account Containers, you can mix and match sessions in tabs within the same window, and you'll never get confused because of the indicators. Works perfectly with Tree Style Tabs as well. So happy I switched back to Firefox!

Awesome add-on!
You can set an URL to use a specific container, I love the safety and privacy this add-on brings!
I wish I knew this before, a friend of mine told me about it.

Estupendo!, usando esta extensión puedo tener varias cuentas en una misma pagina abiertas al mismo tiempo!
