WebKit – an Apple-developed, open-sourced rendering platform – is picking up steam on desktop. On laptop and desktop computers, WebKit-powered browsers are closing in on Mozilla’s Firefox, which is the world’s second most-popular browser. Look no further than Net Applications’ numbers derived by monitoring more than 40,000 websites in their network (see above chart). Adding May 2011 web usage share numbers for Safari (7.28 percent) and Chrome (12.52 percent) brings us to the combined 19.8 percent market share.
That’s just shy of one fifth of all desktop browsing, putting WebKit within spitting distance of Firefox’s 21.71 market share. Trends do not favor browser vendors who have been pretty much bleeding market share to Google and Apple in past months. Chrome and Safari have managed to grow their user base over the past couple of months at the expense of Mozilla’s Firefox, Microsoft’s Internet Explorer and Opera Software’s Opera. A StatCounter survey supports those findings (see below). Why is Mozilla failing?
