Super easy to use! Just download, activate and refresh any open tabs. Very easy to switch between modes (gray & color).

Didn't work at first but when I refreshed the pages it worked perfectly! Great extension!

Hagan que la extensión recuerde cuales páginas el usuario quiere tener en blanco y negro y cuales no, que no sea todas a color o todas en blanco y negro, así se ahorra tiempo

works perfect i dont know why others say otherwise

does NOT work

Didn't work.

Works.

It works why? because it works.

Обожаю монохромный режим, расширение супер

This is amazing! It is so nice that I can turn on and off the monochrome mone in one click, unlike other similar extensions. Thank you for making this, it helped me concentrate on studying.

Well done! It's the best extension for turning webpage grayscale.
