According to the testing, the click-fraud catch rates are as follows: IE9 at 96.6%, followed by Chrome at 1.6%, Firefox at 0.8% and Safari at 0.7%. The lab notes the average lifespan of a click fraud URL was 32 hours with over 50% expiring within 54 hours.
NSS Labs recommends that ad buyers "put pressure on Google to increase the click fraud protection capabilities of Chrome and the SafeBrowsing API."
