Brilliant! There's also a little bug that makes the output blurred, but I like it because it's only blurred enough to make me want to spend less time on the page, but not enough to cause any sort of problem.

not working perfectly ... i add facebook and youtube to auto turn into black and white mode but it cant transfer automatically as by default.... every single time i have to manually turn on the black and white mode ...

cool, it helps me read on some colored website. But it doesn't work on some website.

Modified black and white color intensity are better
