Safari - Display Favicons In Favorites Bar

Is it possible to display favicons in Safari's Favorites Bar? For example, my Favorites Bar in Firefox looks like this:

I've tried using glims, but can't get it to do this.

I was looking for something similar as I use the Chrome bookmark bar in that way, but I couldn't find anything suitable. So I made an extension and have submitted it to Apple, Favicon Bar:

I don't believe that it can be done as of in Safari 8.

In Chrome, you can simply remove the name associated with the site bookmark and it will only show the favicon in the Bookmarks Bar. Unfortunately, doing this in Safari results in a bar of "NO_TITLE" instead.
