Related: The Print Edit add-on for Firefox, which has been doing something similar for over 5 years, and which I think also acts on DOM elements: https://addons.mozilla.org/en-US/firefox/addon/print-edit/ https://addons.mozilla.org/en-US/firefox/addon/print-edit/ It allows you to edit the elements in a page before printing or saving (as PDF, JPG, etc.). You can remove them, alter them, reformat them, inspect them, print a single element (like FF 41 will do) and do much more. It's an amazingly sophisticated add-on that I'm underselling; I encourage you to read the link or simply try it. It's a wonder to use and the most impressive add-on I've seen.
