Browser Market Share, December 2011

Here is the browser market share for December 2011, based on traffic to my top site (number in parentheses shows change from November 2011):

IE: 34.65% (+0.09%)
Firefox: 32.33% (-0.87%)
Google Chrome: 28.49% (+0.62%)
Safari: 1.91% (-0.02%)
Opera: 1.62% (+0.14%)

During the last month of 2011, Firefox was the big loser, losing almost a full percentage point. IE reversed its decline in previous months and actually gained 0.09%. It’s a small increase, but it’s the first time in 4 months that it did not lose at least 1.25%, so it’s a fairly significant development. Google Chrome again was the overall gainer during the month, but its 0.62% increase was the smallest since July.

Since we are at the end of the year, let’s also take a look at the year-to-year comparison between December 2010 and December 2011:

IE: -6.98%
Firefox: -3.79%
Google Chrome: +10.25%
Safari: +0.11%
Opera: -0.15%

Clearly, among the big 3, Google Chrome gained market share at the expense of both IE and Firefox. On the other hand, the last two months have seen Google Chrome’s increase slowing down. Right now it’s not clear whether that’s only temporary or is that a sign that Google Chrome’s momentum is slowing down. We will find out in 2012.
