A favicon (short for favorites icon), also known as a shortcut icon, Web site icon, URL icon, or bookmark icon, is a file containing one or more small icons, most commonly 16×16 pixels, associated with a particular Website. In Magento we have a beautifulfavicon, that represents Magento logo. If you want your own favicon to be displayed on your site, you need to change the default one with the one that represents your site logo.
Generally, all the sites and CMS have their favicon in the root directory of the site, in Magento, it has favicon in six other places to displayed the icon different for each section. Lets say, If you want a different icon to be displayed in your frontend user section and other in the admin section, you have provision for that in Magento.
You need to replace the favicon.ico in the following locations.
If you are not confident of changing the files, Magento has a backend interface throught which you can change the favicon for the frontend site.
Login to the admin section and navigate to 'system -> configuration -> General -> Design'. Select the third tab saying 'HTML Head'. In the first field you can browser your local system and upload the favicon file to be displayed on your site.
