This is an absolute game-changer.
It is unique to Firefox, and one of the reasons I will never switch to another browser.

Allows containers for different accounts.

Remember to get the "Facebook container" add-on as well!

Five stars!

Super useful

Great add-on.
I would like more colors and icons .

Es una extensión excelente, normalmente podrías abrir una sesión privada, pero cuando se tiene que abrir una misma página con más de 2 usuarios, ahí el problema solo se puede solucionar con este plugin. Tener varios navegadores abiertos solo por tener más de 2 cuentas es ineficiente.

Work. Three client accounts. All on the same system. For a couple of years now they've had colours and names. Problem solved.

Lol it must be not reopen it must be refresh, also it must be refresh right and left tabs with container, all you need to be teached:) Good extension, thanks
