Rated 4 out of 5 stars

Its really nice. Shiny and clear indeed. Only one thing i really hate about it. Folder icons and bookmark icons are the same! You have to click on a folder (especially in the bookmarks toolbar) in order for it to open and change its icon to a left arrow. It's the only way to realize it's actually a folder and not a bookmark. The arrow could always be visible even in closed folders or perhaps folders could have a darker color or something. It would be much more clear...
