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!

简单大方

Nice and simple gradient - not distracting.

Clean and beautiful, doesn't have those unnecessary flashy details.
