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.

Extremely useful. It would be nice if there were some more options such as:
- always associate a container with a dedicated window
- associate a container with a dedicated subset of bookmarks
A good guideline for future development might be to make containers work more like the traditional user profiles.
