So as of January 2017, Google Chrome browser was used by 44.5% of internet users. The second most used browser? As popular as Internet Explorer used to be, it has fallen behind Safari. Which is preferred by 25.4% of internet users. IE is now third with 15.5% of internet users preferring it. Firefox is 4th with 7.5% users. So has google officially won the browser war? Right now I'd say they definitely have.
