Clean and efficient Puntuado con 5 de 5 estrellas

It is the only Chrome-like theme I have installed into Firefox. So far I have noticed it has some "poetic license" as to it is not the _exact_ implementation of Chrome's look, on which I have no complaints.
One of examples is that the overall colour is more metal-ly and the close button on tabs does not progressively shift on mouse-over which might be the direct result of how Firefox handles these GUI events.

However, I would like to point out some of the unusual quirks I've encountered mainly regarding notification pop-ups, such as the "Password save", "Addon download", and "Bookmark" dialogs which, for some reason, refuse to open most of the time. An icon is present to notify me of the dialogue box, but my attempts to harness any kind of reaction just ends in failure.
Furthermore, once a dialogue box (on rare occasions) is opened it is without a border and using a plain white background.

That is all.

EDIT: I'm running GNU+Linux.
(EDIT)²: 21-b4 solves the issues! You are my sunshine, dkgo.
