Sometimes you just want a favicon without the fuss. Less importance is being placed on Favicons these days, and we need not care about them that much.
You should always include the blank Favicon <link> directive on every page, aswell as a real favicon in the root of your domain. You needn't put much effort into creating teh perfect favicon.
Include this on every page:
<link href="data:image/x-icon;base64,iVBORw0KGgoAAAANSUhEUgAAABAAAAAQEAYAAABPYyMiAAAABmJLR0T///////8JWPfcAAAACXBIWXMAAABIAAAASABGyWs+AAAAF0lEQVRIx2NgGAWjYBSMglEwCkbBSAcACBAAAeaR9cIAAAAASUVORK5CYII=" rel="icon" type="image/x-icon" />
