Pencil is a nice and simple ( i.e. not Visio ) add-on for Firefox which allows for drawing a quick diagram or even a basic application UI's. It supports drag and drop, it's free and it only requires Firefox 3.
Once install it's available as a link off the Tools menu.
It was one of the 3 Best New Add-on's in the Extend Firefox 3 Contest
