I really don't think this captures the scope of the problem. Here's an example: 1: Load NBC.com (or any other regular media site) in a "naked" web browser (just a plain browser, no ad blocking, noscript etc) 2: Open dev tools -> networking tab 3: Study the activity, look at requests made, size of requests, data the requests contain (remember, YOU are paying for these requests in terms of impact to battery, bandwidth, electricity usage etc) I can see MB's of data transferred from my device, every time I scroll more network activity is performed (100's of requests per MINUTE), this is all made possible by "JS" which is the single biggest resource hog of any modern browser. Turning JS off (whilst obviously crippling some pages) results in HUGE savings of bandwidth, reducing battery impact AND increasing privacy :). (You can also use noscript to allow/deny certain scripts from loading, and you'll be surprised how many pages work with JUST the root domain enabled, thus every third party script is not vital to the functioning of the page) I seriously think modern browsers (including Firefox) need to implement features to reduce the amount of network requests a page can make, including to third party websites, and limit the amount of data a single page can consume. I'd call it a "browser firewall" similar to tracking mode, preventing third party requests entirely Data does cost, contrary to what others make think, especially on mobile lines when out and about. So yeah, let's fix that first.
