Does the job but as the description says, unlike FB container, doesn't prevent you from opening links in the wrong container and this kind of defeats its purpose. Additionally, after I carefully created a number of containers, it mysteriously forgot all of them and reset itself to its initial state. Not cool.

Excelente alternativa, me ha ayudado a abrir varias sesiones de un sitio web y agrupar los que visito con frecuencia.

I love this extension, just wish it would sync between computers

I really love this extension. The biggest problem is that containers and settings do not sync with Firefox Sync.
