Remember a few months back when I brought your attention to del.icio.us? Well, if you started using del.icio.us like I did, and you use Firefox like I do, you should totally pick up the Foxylicious Firefox Extension. What it does is take all the tags you applied to your bookmarks on del.icio.us and create an actual list of foldered bookmarks in you Firefox bookmarks list. So now you can see all your bookmarks, sorted and organized the way you intended them to be in Firefox.
Greatest Firefox Extension ever.
