I want to show logo on the address bar. But it is visible only on tab next to title.
<link rel="icon" href="http://www.mydomain.info/favicon.ico" type="image/x-icon" />
<link rel="shortcut icon" href="http://www.mydomain.info/favicon.ico" type="image/x-icon" />
Short answer: yes. That's how many browsers work.
Firefox: http://msujaws.wordpress.com/2012/04/23/an-update-to-site-identity-in-desktop-firefox/
Chrome: why doesn't the favicon file show in the address bar of google chrome? and http://productforums.google.com/forum/#!topic/chrome/kUQOKVUwUmw
In the wikipedia page, you can find some more about browser support. In short, Firefox and Chrome don't do it, Explorer, Safari and Opera do.
