Breadcrumbs Chrome Extension

Baffling. When you click on the extension button it pops up a window asking you to enter a code. There is no explanation as to what this means, at all. The extension's Chrome store page didn't explain what this meant. A Google search didn't reveal what this meant either. Aside from asking you for this code, the extension does nothing at all. What a waste of everybody's time, I hope you are proud of yourselves.
