@bitnix: Yeah, which is a pain when making a bookmarklet that opens a new window for editing the post; then you're left with two windows with the same page. I find the auto-closing Facebook Share bookmarklet much more elegant.

Geira: On the other hand, though, finishing posting a bookmark on del.icio.us will bring you back where you were.

Yeah, we all know that it's possible to use a bookmarklet. It's also rather tedious. With the widget you don't lose the page you're bookmarking, so you can switch between the windows to copy text for the description. However, nothing beats the Firefox plugin where you can just select a text block which it automagically uses for the description.

You don't need an extra application for that, just add the following snippet to your bookmarks:

javascript:location.href='http://del.icio.us/post?v=4;url='+encodeURIComponent(location.href)+';title='+encodeURIComponent(document.title)
