Version 7.3.0 On MacOS missing hide/show container functionality. I joined a discuss/question on the matter with support. For me, this is very valuable functionality. I will gladly upgrade rating once resolved.

EDIT: Thank you for the Developer response. The "## >" on the right of each container is a Button that takes you to more options, which include "Hide"

The only thing missing for a 5 star, personally, would be the ability to set the order of the sorting of tabs

I hope I can add '*.example.com' pattern in containers' site lists.

it does about what you would expect, though there are some serious UX issues I wouldn't have expected from an "official" plug-in. Particularly in regard to the "Always open in this container" feature. You would think after so many complaints/github-issues like #1999 (https://github.com/mozilla/multi-account-containers/issues/1999) about it being hard to undo, they would've done something. Can't in good faith rate this five stars until they fix this, but it's still a decent add-on either way.

Incredible when it comes to privacy and security, but it does have it's quirks. For example you can't add websites to containers by simply typing the url to the website in and you can't add a website and it's sub-domains until you can reach the original website itself (and some websites automatically redirect you to a sign-in subdomain, for example Microsoft)
It is also quite glitchy sometimes. Randomly closing tabs rarely.
It's very good however as websites are limited to their own containers and the switch to containers is pretty seamless.

Excellente extension pour compartimenter les activités entre plusieurs profils sans utiliser plusieurs navigateurs. Très utile, notamment à l'ére du télétravail !

Отличный способ ни использовать кучу браузеров и быть залогиненным на одном сайте под несколькими аккаунтами одновременно.
