If you haven't seen it yet, the "Shooter" addon for firefox basically does this same sort of thing (screenshot of page by using the canvas). https://addons.mozilla.org/en-US/firefox/addon/shooter/ https://addons.mozilla.org/en-US/firefox/addon/shooter/ The only real bug I've seen in it is the use of white as the default background color in pages, with all page styles (and css files) loaded on top... This means it's (properly?) ignoring the user defined page background color.
