The idea is perfect but the actual add-on could need more colors (20 would be good, at the moment the add-on has 8) and especially more icons (40 would be good, at the moment the add-on has 13). However im grateful Mozilla does us a favor with their software :)

Would be perfect if the option to ask to choose a container when creating a new tab by clicking on the tab bar, would also apply to the keyboard shortcut (CTRL + T)

This add-ons does not sync the tabs in chronological order as user has defined.
It should sync correctly on another device also.

Good extension, but need redesign and responsible design, and zoom settings too

Works very well. I would like to be able to use different containers depending on the account for a website (eg. I have separate work and personal emails).

Great but not enough icons (and colors) !

This is a very good extension. I like to have my work sites and browsing separated from personal sites and browsing.

The only thing I'd love to see is the ability to choose groups to re-open. For example, I would love to be able to choose to re-open both my personal and work tabs and windows, or to be able to choose to just open my work tabs and windows or personal tabs and windows.

Please add a feature to always open certain bookmark in a specific container.

Debido a la funcionalidad de administración de contenedores muy limitada, el complemento es casi inutilizable en muchos sitios como bancos, Microsoft, AliExpress, eBay, etc., que utilizan redirecciones a otros [sub] dominios para realizar un inicio de sesión, para transferir al usuario a un servicio de pago, etc. La redirección a veces se realiza varias veces, por lo que es posible que el complemento no pueda permitirle al usuario establecer correspondencia de dominio con el contenedor. En tales casos, la única forma de trabajar con éxito con el sitio es eliminarlo de los contenedores y usarlo solo.

La solución es trivial: permitir que el usuario ingrese / edite el nombre de dominio manualmente, con soporte de comodines (*). Esto resolvería la mayoría de los problemas descritos anteriormente.

[ORIGINAL 1 Star]Working adequately until today. Now Firefox 88 on Windows 10 will not load with this plugin enabled.[/]
Firefox updated to 89, so I enabled M-A Containers once more and the plugin seems to be working fine again.

I want to manually add websites, because it can be annoying to get to the website sometimes. But overall good extension.

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.

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.

De oplossing om aan te melden bij verschillende e-mailboxen van dezelfde provider. Bespaart een hoop ergernis en maakt het super simpel zonder iedere keer af te melden bij schakelen naar een ander e-mail account.

Everything fine with this new feature like Multi-Account Containers but I can just add that I if you can do something with the history by container can help to no loose the different webpages that I visited, because the container just safe the current page where was my last visit, it doesn't show me the movements forward and behid that I made.

Hiding Containers don't work anymore

a bit finicky to set up
