"Irrelevant" is a strong, dismissive word that comes with a certain arrogance that I don't think fits the facts at all in this case. The author said FF became irrelevant after 2008, which is false. It was popular for a long time after. The answer to the question "how popular is a browser" should not be answered by anything other than stats for your own sites. Global stats don't interest me. While Chrome certainly did rise in popularity and overtake FF, it was absolutely not in 2008 that happened according to the browser stats of the network of mainstream popular sites I worked on for a few years at that time. I do remember seeing a discrepancy in the "global stats" vs the actual stats from Google analytics I was accessing on a regular basis, which told a different story.
