I could really use a good tug, I think I'll use Firefucks.
An add-on for mozilla firefox which allows the user to download an entire catalogue of small .mpeg files from an x-rated website and sort them all into the correct order, adjust them all to the same volume level, then play them sequentially, all with a single click so the user can keep one hand free for other things.
