Quinn's dashboard

Ok, from my understanding of things I should be able to sync my Delicious bookmarks to my Firefox. I recently switched computers, and through a misunderstanding with the guy who was trying to fix my old one, the hard drive was wiped before I could retrieve any of my data, so I'd really like to have my bookmarks back in my browser. I can't figure it out. I have the Delicious extension for Firefox and I tried to use the Full Sync button in the options, but nothing happened.
