We need a Firefox-Addon. This should have an icon. After clicking the icon there should come a small layer over the website with an iframe, a picture and a button in it.
After clicking the button, the Addon should create a new bookmark-folder with a bookmark of the current website.

I can make this in one day. I am not an artist and cannot make a professional looking icon, but I can use a free one, or use the icon that you may provide yourself.
