Add Favicons to External Links - Bookmarklet

This little JavaScript bookmarklet will add favicons and some CSS styles to all external hyperlinks on a web page. The favicon images of a website are fetched using Google’s favicon generator that was originally part of Google Reader. And here are some more useful bookmarklets for your browser.

// Highlight External Links by Amit Agarwal

// Find the domain name of the current page
var host =;

// Use Google's Favicon Generator
var goog = '';

// Find all hyperlinks on a web page
var links = document.getElementsByTagName('a');

for (i = 0; i < links.length; i++) {
  var link = links[i];

  // Skip all internal links where the href is the same as the domain host
  // Also skip non HTTP links like FTP, MAILTO, etc.

  if (link.href.match('^https?://') && !link.href.match(host)) {
    var domain = link.href.split('/');

    // Apply some CSS styles to the external hyperlinks = 'url(' + goog + domain[2] + ') center left no-repeat'; = 'bold'; = '105%'; = '5px 5px 5px 20px'; = 'underline';
