An enterprising group of young coders have developed a Firefox add-on which does something rather worrying – adds ‘Download 4 Free’ buttons to Amazon pages. When you click the button, it’ll work out what product you’re looking for, and take you to a page on the Pirate Bay that’ll let you download it for free.

It works for CDs, DVDs, games, books and any other product that can be converted to a digital format. The team behind it claim they want the extension to “be a counterpart to the current models of media distribution”, and to “redistribute the wealth”. I’m not sure that’ll wash before a judge, to be honest.
