Martin Borgert uses my gtk-vector-screenshot application to take screenshots of a web page opened in the browser, in his case, epiphany. I find this a very good idea and was surprised to hear that it works flawlessly: The rendered web page not only shows up, it even shows up as vector graphic with fully selectable text. It’s also neat that a HTML5 video appears.
One feature that is hard to replicate with regular screenshots is taking a shot of a window that is larger than the current screen. This PDF file (of which the image on the left is a thumbnail preview) contains a whole web page that would not fit on my screen. To achieve that you need a window manager that allows resizing windows beyond the size of your screen (e.g. xmonad). Then just keep resizing and moving the window until the scroll bar disappears and take the shot.
BTW, gtk-vector-screenshot is available in Debian unstable.
