One report: what did this page actually do to me?

Over the last several releases the browser gained a set of tools for seeing what a page is really doing behind the scenes: what its scripts did, how much of everything it downloaded actually showed up on screen, and whether it tried to fingerprint you. This pulls them into a single report you can run on a saved page and get the whole picture at once - how many scripts it ran, how much of its download was pure weight that painted nothing, and how many times it tried to fingerprint you - all sealed into one result anyone can re-check offline. It is one honest answer to the question behind all of these tools: what did this page actually do to me?

Privacy & Shields	A single report brings together the three checks added recently - the scripts a page ran, how much of its download painted nothing, and its fingerprinting attempts - so you get the whole behind-the-scenes picture in one place.
Privacy & Shields	It runs on a saved page, entirely offline, and the whole report is sealed into one result that anyone can re-check and that comes out the same every time.
Privacy & Shields	Each part is still available on its own, but the combined report is the quick answer to 'is this page doing anything I should know about?' without running several separate checks.
