Delicious offers the option for both importing existing bookmarks to your Delicious account, as well as exporting your Delicious bookmarks into your browser. If you have bookmarks in your browser that you'd like to upload, you can use import/upload in your Settings to add them to your account. You can upload as many bookmarks files as you like, one at a time. This can be convenient for consolidating bookmarks from multiple computers. You can use the export/backup tool, also in your Settings, to make a copy of your bookmarks and tags that you can then import into your browser (or something else). In addition, Delicious will also ask if you would like to include new bookmarks in Delicious should you choose to use the standard way of creating a book mark through your browser window. Realize this only occurs if you have added the browser add-ins.
