Debería de dejar descargar las imágenes de instagram, al menos en Firefox, ya que la forma de descargar las imágenes de la pagina web, no es muy complicado si se accede a la información de la pagina web.
Assuming the translation by google is correct: I won't build site-specific support into this tool. It's meant to be a generic image downloader that works well on sites with conventional HTML structures that expose images in an accessible way. Instagram is one of those sites with overly complicated, image-hiding webpage structures. I find a 2-star rating just for not working well on instagram a bit superficial since there's so much more to this addon and it works fine on most websites, but ok.
