I like this theme, its simple, and comfortable for me. it looks nice. Its just perfect.

Supports 21:9 UltraWide :)

Very nice, calm theme. Seems to have trouble with the most recent FF versions. Like 60.0b8 (64-bit). It has to be reinstalled every session.

nice plain but pretty backgrounds

Simple et clair

looks pretty nice on my desktop, but a little too glossy

Firefox responds quickly & allows me to save time.

Mega, tolle Farben!
