Digital Trends – According to data provided by StatCounter, Google Chrome is currently in position to rise above Mozillaâs Firefox and become the second most popular Web browser by December 2011. Googleâs aggressive advertising for the speedy browser has helped growth over 2011. Starting with 15 percent of the market share in January 2011, Googleâs current market share has risen to 23.6 percent as of September 2011. Googleâs rapid gain in market share is likely attributed to users defecting from Internet Explorer and Firefox. Microsoftâs user share has dropped from about 46 percent at the start of the year down to 42 percent and Mozillaâs user share has dropped a little over five percent in the same time period.
