For everyone using Firefox and del.icio.us, Foxylicious is a very wonderful extension. I was searching on Google for tips on how to back up del.icio.us bookmarks when I came across this article.
I have installed the extension and it works! The coolness of it all is that I don't have to log in to del.icio.us everytime I want to access my bookmarks when I am using my computer in the office.
I just love del.icio.us and Firefox so much!
