If you don’t know what I’m talking about, favicons are the small icons which most websites use to distinguish themselves from all run-of-the-mill Internet Explorer icons which show up beside the name of the page on your browser tab or in your Favorites list.
I didn’t realize how useful favicons were until I installed Internet Explorer 7 and they all disappeared. When you have a thousand Favorites in dozens of folders, the little favicons make it easier to locate links. A long list of blue IE icons is visual overkill.
Microsoft invented the favicon but handles it poorly in Internet Explorer, they disappear when you clean out your Internet temp files or for no apparent reason at all. Firefox is better at it.
Restore your IE favicons using the free Favorg program – get it by clicking here:
It works very well with IE7, IE6 and IE5. It also lets you know which of your Favorites are dead links or have been redirected.
Theoretically, Favorg is not Vista compatible, however, it installs and runs with no problem even in 64-bit Vista.

If you wish to use the Favorg Help Menu in Vista you’ll need to download and install a Windows Help (WinHlp32.exe) file from here. Microsoft have changed the Help program for Vista.
The program is self explanatory, so you probably won’t need to go to that trouble.
Extract from FavOrg’s Help file:
What is a favicon by the way? Internet Explorer will always look for a file named favicon.ico in the root folder of any site to which you connect. For example, if you connect to:
http://www.thissite.com/programs/freeware/index.htm, the favicon URL should be http://www.thissite.com/favicon.ico. If IE finds such a file, it will download it as soon as you create a new item for this site in your favorites folder (Add to favorites… command). This icon will be assigned to the corresponding shortcut automatically. You’ll see that a favicon is sometimes not an actual icon but a bitmap (which sometimes leads to minor display problems).
So, why do we need a utility to manage these favicons? Because Internet Explorer doesn’t do its job very well. The downloaded icon file is stored as a temporary file. Which means that after a while, the favicon will disappear and your shortcut will be associated again with the standard Internet Explorer icon. This often happens after cleaning up your Temporary Internet Files folder. FavOrg will fix this problem and ensure that your favicons are made sticky. That is, once downloaded, the icon will be assigned to the shortcut permanently. FavOrg stores the favicons in a user-defined folder.
Also, for unknown reasons, Internet Explorer sometimes fails to automatically download the favicon. FavOrg will check any Internet shortcut in your favorites folder and will automatically download and install the favicon if it is present on that particular Web site.
FavOrg will also allows you to assign a custom icon to any of your Internet favorites, even if there’s no favicon downloadable from the corresponding Web site.
Finally, since FavOrg must check the validity of an Internet shortcut before trying to download the corresponding favicon (if any), this is a good opportunity to find which of your favorites links are broken. FavOrg will report dead sites, removed or moved pages and will also be able to automatically reset a link to the site’s root page (if a page has been removed) or to update a link to a page that has been relocated.
