What could cause a page opened on Firefox to have an enormous data usage? I have opened the rather innocuous page on reputable website Quanta Magazine using Firefox Android 65.0.1 (with NoScript installed) and left it open.

The data usage rapidly burned through 1 GB of data transfer via the mobile network, which is more than I use in a month in general.

I closed the page, stopping data usage. Reopened it, and on it went. It has blown my data usage for the month out of the water.

I have pumped the URL through Sucuri just to make sure whether there is a known evil in that page but it comes up blank.

What could be going on, and do I find out?
