I won't waste time by repeating all the benefits already pointed out by other reviewers here; but what I am going to add is that this addon has a BACKUP option that you can use to safely store all the bookmarks that you have painstakingly added one by one, so in the event of a data crash you can simply restore them (unlike another popular new tab page that shows quite fancy wallpapers but does not even allow backups! I had tons of bookmarks there but lost all of them and cannot get them back.)
