Rated 5 out of 5 stars

My 5 stars is for a slightly older version 1.8.37. With this, I can squeeze 69 favicons (mini-icons in address bar) on my bookmarks toolbar by deleting their name and recognizing the icon alone. The newer version adds extra space between the the icons and I can't fit nearly enough. Great screen real estate saver and fav theme!
