With only a few JavaScript lines you can initiate the dialog for "Add to Favorites" dialog in Internet Explorer and the "Add to Bookmarks" dialog in Firefox, as shown in this example.

1. <script type=“text/javascript”>
2. var BookmarkURL=“http://www.geekpedia.com”
3. var BookmarkTitle=“Geekpedia”
5. // If the browser is Internet Explorer
6. if (document.all)
7. {
8.  // Add to Favorites (Internet Explorer)
9.         window.external.AddFavorite(BookmarkURL,BookmarkTitle)
10. }
11. else
12. {
13.  // Add to Bookmarks (Mozilla Firefox)
14.         window.sidebar.addPanel(BookmarkTitle, BookmarkURL, ”);
15. }
16. </script>
