I originally read about this in the post you linked. There were some great charts in that article showing how performance has changed throughout the version of Firefox. I only clicked this article because I was hoping to see a direct comparison to Chrome laid out in similar fashion. Unfortunately, the title is purely click bait and the only mention of Chrome is that anecdotally, "Chrome has something of a reputation for being a resource hog".
The article that was originally posted was certainly more interesting and informative.
