Lake Vibes by Ghost

A simple, clean browser theme for Firefox. Shades of a dark cerulean blue, black, white, light and dark gray were chosen in order to evoke lake water at night- the dark blue depths and the silvery light of the moon reflecting on it; the sounds of the waves stretching out into a quiet, starry evening.
I chose "Solid" as the category for this theme because the background color is solid, and no background images/gifs/animations/textures are used.
