Only used for a day, but thus far it's perfect. Love the color customization, it's not in-depth but it's just enough to set it somewhere comfortable for your eyes. It's also smart enough to correct embedded white backdrops, unlike the other version I tried. Awesome!

Tuts wieder, klasse.

GREAT

Edit: Loading issues seem to have been resolved!

I'm also having issues with the latest update breaking page loading. Hoping this gets the dev's attention and will happily revise to 5 stars when resolved!

this extension solves a surprisingly hard problem surprisingly well. It just works.

Black out the EARTH. Thank you.

does it's job perfectly. firefox must include some addones in it by default and ask the user on installation a fresh copy whether or not you want to enable it
