Windows only: System utility FavIconizer fixes your Internet Explorer bookmarks, bringing back missing Favions to your favourites toolbar.Using the application (which requires no installation) is as simple as pushing the Find missing FavIcons button. Your bookmarks will be scanned and any missing icons will be populated, or you can choose to rescan all of the links in case Google updates their favicon again. This utility might come in handy for Internet Explorer users frustrated with icons disappearing randomly over time, or not showing up in the first place. FavIconizer is a free download, Windows with Internet Explorer only. Firefox users can customise any favicon with the previously mentioned Favicon Picker extension.
