Mobile phones in China and Taiwan follow similar patterns: For pageviews from Android, 0.4% disabled JavaScript in both China and Taiwan, and no one (!) on iPhones disabled JavaScript from either country. Pageviews from desktop users had JavaScript disabled at roughly the same rate in both China (2.5%) and Taiwan (2.6%), but lower in South Korea (1.9%). These high rates are important, and they are doubly interesting when we breakdown the aggregate numbers by device type. Traffic from Taiwan, China, and South Korea had JavaScript disabled at 2.3%, 1.9%, and 1.4% of pageviews, respectively, placing them as the top countries worldwide that disable JavaScript after Tor users. However, the traffic from Tor users was a tiny percentage of the worldwide traffic Blockmetry measured in Q4, so the impact of this high rate is negligible to the overall figures. Websites that attract sizeable volumes of Tor traffic need to take note. Tor users disable JavaScript the mostĪ somewhat unsurprising finding is that 10.5% of pageviews from Tor visitors disable JavaScript. The next question is: Who disables JavaScript at high rates? The answer is Tor users, east Asian countries, Africa, and Finland. Although apparently tiny, the aggregate figure hides a lot of interesting variation and regional patterns, with traffic from some countries having much higher JavaScript disabled rates.įurther, cross-tabulating by device type, traffic from desktops, Android phones and Android tablets had the highest rates of disabling JavaScript, while iPhones and iPads generally had lower rates. So the obvious question arises… What percentage of browsers have JavaScript disabled?įrom Blockmetry’s direct measurements, 0.2% of pageviews from worldwide traffic across all devices in the fourth quarter 2016 had javascript disabled.
Blockmetry measures them using a
