In just a year, Internet Explorer usage is decreased by 6.12%. In the same time period, Firefox usage is also decreased by 1.68%. On the other hand, Google Chrome market shares jumped from 5.22% to 10.70%. so, it is now cleared the users are preferring Google Chrome over Internet Explorer and Firefox.
