Have you tried using canvas? drawWindow will let you could use to draw the page to the canvas (this window does not have to be visible, it could be the contentWindow from an invisible iframe for example) getImageData could then be used to retrieve the image data off the canvas (note: this might be harder to do if you aren't planning on doing it from Javascript because canvas gets the arguments from XPConnect).
