How do I uninstall the Firefox or Internet Explorer Add-on?
It depends on which ones you have installed. Here are the instructions for both kinds, but you probably only have one of them: A. To uninstall the Internet Explorer buttons, go to Add or Remove Programs and uninstall “Delicious Add-on for Internet Explorer”. B. To uninstall the Firefox add-on, go to Tools->Add-ons and click the “uninstall” button for the Delicious Bookmarks add-on.
