Add link to Delicious
WARNING: Unfortunately Delicious has been discontinued since June 15, 2017. https://blog.pinboard.in/2017/06/pinboard_acquires_delicious/
So I suggest you migrate to pinboard or other similar service! http://alternativeto.net/software/delicious/
If you'd like to migrate to Google Bookmarks, export the HTML and import with the following links:
1) To export from delicious use: http://del.icio.us/export
2) To import into Google Bookmarks from delicious use (Upload HTML): http://google.com/bookmarks/deliciousimport
The original code for this extension is on https://del.icio.us/tools.
You can see the source code on github and contact me there as well: https://github.com/leocaseiro/AddToDelicious
