Simply awesome. Discret and efficient, you only notice this extension is installed when you needed, then you just use it.

When is the expansion update coming? Will something new be added?

I have been using this to load my AWS profiles. The best extension there is!

Very useful extension. I just wish you could open a temporary container tab when opening a new tab. As of now you can only open a temporary container tab when right clicking a link.

Não sei como não comecei a usar antes! Muito bom para separar os acessos e logins em serviços específicos em que tenho mais de uma conta. Migrei de vez para o Firefox com esse add-on!
(Só falta ter uma versão pra Android agora...)

Absolutely necessary Extention to everybody! It helps me to isolate my workspaces easily, and I don't have to think about shared cookies across different profiles!

This extension allowed me to migrate from Google Chrome and its Profiles (each one in a separate window) to Firefox... and now I can have everything in a single window.
