Outfoxed looks really cool (via Waxy Links), but unfortunately, Outfoxed only runs on Windows (since most of Outfoxed is a Firefox extension, the user interface works, but the MDDB server needs to be built if you are using Linux, which is annoying to those used to the traditional fire-and-forget method of installing Mozilla extensions. If I was using Debian and not Ubuntu, it would be relatively easy to get most of the packages and install them, but I have still not expended the time to properly figure out how to compile Debian packages. Assuming that Outfoxed does not appear in an Ubuntu package between now and June, I will take a look at this over the summer.
