What is this SF Visual Search thing on my online store?

I found this what looks like a plugin on my online store and I have no idea how to remove it. It only appears in product detail page: http://heavenlynature.co.nz/shop/shower/berry-chocolate-dessert-soap So far I have only found this plugin appear on Windows 7, Firefox 19. Can anyone shed a light?
