If you use dark themes this is an essential add-on. Works perfectly most of the time. it's configurable. I use to use a custom styles sheet but this is vastly better. It dims images and just darkens the pages without drastically changing the layout or content.

it's in my essential add-on pack. it works wonderfully seamless and with minimum clutter.

very nice

Great extention! It works fine on many sites, but some (like imdb) clinches with Firefox/Mozilla.

An excellent add-on. This add-on provides a comfortable environment for reading all kinds of web pages, especially for those who need to do research and read online for a long time or at night.

Ok

Must have in the World of "White Madness" we currently live in.
