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.
It is up to the browser to decide where/whether to display a favicon.
Chrome reserved the addressbar for the address and an indication of the protocol.
There is not much you can do about it.
