Excelente extensão.
Agora consigo abrir mais de uma conta do Whatsapp ou outros sites ao mesmo tempo.
Com essa extensão, não é necessário abrir um outro navegador ou aba anônima.
Parabéns ao Firefox.

Been using multi-account containers for a few years now. Don't know what I'd do without it now.
One feature I wish they would add is to be able to delete cookies, etc. by container leaving other containers alone.

Useful and needed in modern web browsing to separate your personal data out of big brothers.

这简直就是我用firefox的唯一原因，这个插件太棒了

Very convenient to automatically open each of my websites in its own containers as defined in the configuration.
