This is now one of my must-have add-ons!

I am so happy to find this extension and switched to firefox for it. it really helps me with aws accounts.

Perfect for keeping youtube accounts and stuff like that separated by tab.

Dev/Test/Prod - works great for me keeping them straight.

Mozilla nın tavsiyelerinde buldum bu eklentiyi. Çok memnun kaldım. Kullanmaktan büyük keyif alıyorum. Birden fazla hesapla çalışmanız gerekiyorsa bu uygulama hepsine yeter.

Es la única extensión que realmente funciona. He probado muchísimas, y ninguna es realmente funcional a excepción de esta, la recomiendo mucho

Most useful addon for me, especially in comparison to other browsers. I am not logged in all the time for example in Google, and can use several accounts of the same online service. And it remembers, which URL should open in which container, if I want.
