Works surprisingly well. Some background images on websites are not displayed but who really needs them

Magical
It just manages to work with every website somehow. The comfort of your eyes. wow! All the screen time spent over a day adds up and this really is an eye-saver.. Email, Facebook, YouTube, Google.. all of these can't hurt my eyes no more!

Muito bom, uso o firefox por causa dessa extensão

Фантастика! Только жаль, что я так долго не находил это расширение.

so beautifull! *-*

Great add-on all around. Helps my eyes, and it looks natural.
