In fact, this is a very aesthetic and beautiful theme that does not interfere with working with browser tabs. However, it seems that it is not designed for 27-inch monitors. Since the image is at the top (where the tabs are), it doesn't take up all the space. Therefore the remaining space is filled with a pale purple color.

Classy and works well with menu readability.

Amo este tema, es super bonito y elegante

love it :) though i'd love a version that gives the firefox menu pages (add-on manager, settings etc) a dark background as well

Elegante y no daña los ojos
