I just released the NoCoffee extension for Chrome today.

It’d be great to make a version of NoCoffee for Firefox and other browsers. I can post the code to that if anyone is interested in taking that on (or improving the extension for that matter).

window.checkBlurKey = function(evt) {
window.blurLevel = (window.blurLevel || 0);
window.blurLevel -= ((evt.charCode == 91/*[*/ && window.blurLevel > 0) ? 1: 0);
window.blurLevel += ((evt.charCode == 93/*]*/) ? 1: 0);
window.updateBlur();
};
window.updateBlur = function() {
var currZoom = window.outerWidth / window.innerWidth;
var adjustedBlur = window.blurLevel / currZoom;
if (document.body.style.webkitFilter) {
document.body.style.webkitFilter =
adjustedBlur ? ‘blur(‘ + adjustedBlur / 2 + ‘px)’ : ”;
} else {
var blur = adjustedBlur ? adjustedBlur : 0;
var filter = ‘url(\’data:image/svg+xml;utf8,#svgBlur\’)';
document.body.style.filter = filter;
}
};
if (window.blurLevel === undefined) {
window.addEventListener(‘keypress’, checkBlurKey);
setInterval(updateBlur, 500); // In case zoom changes
}
window.blurLevel = parseInt(prompt(‘Blur amount (0-20)? \n’ +
‘(Press [ and ] in page to change)’, window.blurLevel || 0));
window.updateBlur();
