Where are your novice training procedures? How does a user push content into different containers? How does a user modify incorrectly filed websites? How does a user access tree structure? Does anyone have a decent tutorial for this addon?

Es muy buena. Debería "preguntar" cuando abre otra pestaña por seguimiento de un link en que contenedor queremos abrirla. Cuando se ingresa a gmail hay que recargar la página, no ingresa en el primer intento

Extremely helpful when needing to concurrently use multiple accounts on systems such as AWS

I can't stress enough what a big game changer this is in turns of usability (log into different accounts at the same time) and privacy protection (separate data between different websites). Obviously we need this to be a first class citizen in Firefox, i.e. each bookmark should be able to specify what default container to open in.

Works flawless

Different profiles in each tap, man I cannot live without it!!! <3
