So far so good and does what it was supposed to.

The fact that it doesn't require any permissions is very nice. For only the sake of having a background image for my new tab page, I installed various extensions and they all needed loads of arbitrary permissions.

The luminosity feature is a bit confusing, but aside from that it's a very good extension.

i love the stupid funny quotes that you can enable and the changing backgrounds are so cool! you can disable and enable them too anyways. 10/10

I highly recommend this extension! I swear, the daily quote is kinda omnipotent and definitely helped me especially on hard and distracting times. Thanks dear kind developer. I wish I can donate you monetarily, I will someday when I graduate<3

Good black screen! Respect!
It's impossible to set wallpaper from harddisk!

Why user must search how to fix trouble with firefox cache, when there is noone other troubles!?!?!?!?!?!???

The worst app, don't install this.
