Due to very limited container management functionality, the add-on is almost unusable on many modern sites like Microsoft, AliExpress, eBay etc.

It is known that many sites use redirections to other [sub]domains to perform a login, to transfer the user to a payment service etc. The redirection may be performed several times, so the add-on may be unable to ask the user to establish domain-to-container correspondence. In such cases, the only way to successfully work with the site, is to remove it from the containers, and use only alone.

The solution is trivial: just to allow the user to enter/edit domain name manually, with wildcard (*) support. This would solve most problems described above. I asked about such feature some time ago, but the request was ignored.

Fantastic. The only reason I continue to use firefox.

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.
