setInterval again. I wonder whether some ad framework recently added a setInterval(..., 0) call to itself.

Every case has a quantcast choice.js loaded, blocking the quantcast domain is bringing these sites back to normal levels of use

This had the same origin as a cpu usage issue on GameRadar i reported in https://bugzilla.mozilla.org/show_bug.cgi?id=1646174 , the website no longer uses the offending blob from Quantcast.
