Pretty good. Shared history among profiles dilutes the usefulness, and the stupid "You've opened 100 container tabs!" interstitial breaks keyboard shortcuts, forcing you to use the mouse to continue. At least that only happens once per installation (unless there are more milestones coming...)

Honestly this is best god damn thing ever

The UI can be a little clumsy in a few places, though for the most part it's useful enough that I'm willing to overlook that. I'm definitely happy that as far as I can tell, tabs in a hidden container are maintained between sessions (assuming you have that option turned on) and can't be accidentally closed with the "close all other tabs" or "close all tabs to the right" buttons. On the other hand, tabs almost never reload properly from the "undo close tab" button, so if I do accidentally press the "close all tabs" button, everything is gone. It's extremely frustrating.

Amazing app. Can you add feature to order the containers so that we can order frequently used container at top?

Muito boa essa extensão!! Estou bastante satisfeito.

Se fosse possivel gostaria que houvesse uma forma de sincronizar as configurações dela entre diferentes firefox's, eu uso essa extensão no computador de casa e do trabalho, mas as alterações que faço em uma não reflete na outra.

Excellent extension!! I'm very happy with it.

The extension could be even better if it has a sync option. I use it in my home and office computers, the changes i do in one doesn't reflect in the other.
