I'm trying to create a bookmarklet for posting del.icio.us bookmarks to a separate account. I tested it from the command line like: wget -O - --no-check-certificate \ "https://seconduser:thepassword@api.del.icio.us/v1/posts/add?url=http://seet.dk&description=test" This works great. I then wanted to create a bookmarklet in my firefox. I googled and found bits and pieces and ended up with: javascript:void( open('https://seconduser:password@api.del.icio.us/v1/posts/add?url=' +encodeURIComponent(location.href) +'&description='+encodeURIComponent(document.title), 'delicious','toolbar=no,width=500,height=250' ) ); But all that happens is that I get this from del.icio.us: If I then go to the address bar and press enter, it changes to: Any ideas how to get it to work directly from the bookmarks?
