Pretty add-on until I found out that for Google these Containers doesn't exist. Searched in another container for something very specific and got related group ads in Facebook container lateron.

Was great untill today, when I have lost my container tab and all my set continers are not showing when opeing a tab

Justo lo que necesitaba para poder brindar soporte a diferentes cuentas, gracias!

Nice, no other browser has this feature. And it made my life easy.
Thanks Firefox.

在“Open this site in your assigned container?”页面，选择后一个选项时，极大概率会出现点击无效果的情况。

Só não vale 5 estrelas porque não funciona no mobile onde eu mais queria.

Very useful! But I would like to be able to sync the configurations between devices, and to have the choice of some predefined rules. Such as "every google page in a Google container". Also, I have a bug when I create such rule on a google page, and that I have a page that automatically redirect to another container page. The new container page is indeed opened in a new tab, but the previous tab is not closed...

no me guarda para las sesiones siguientes las paginas catalogadas para cada contenedor
