Boo Mozilla. Yah jooliaan Rated 4 out of 5 stars
The only thing I don't like is the extra space reserved for the padlock. I think we can do without the space and the padlock and just use the color change for https sites. Also, it doesn't work with link rel="icon" href="data:image/png type favicons. Example: http://xdot.tk/
Site Favicon in Urlbar
If you do not like the padlock, please, give this one https://addons.mozilla.org/en-US/firefox/addon/site-favicon-in-urlbar/ a try.
Hope this help.
