Google's Chrome web browser has overtaken Apple's Safari to become the world's third most popular browser after Mozilla's Firefox and Microsoft's Internet Explorer.
Chrome ended 2009 with a total market share of 4.63%, while Safari ended the year with 4.46% and Firefox with 24.6% of the browser market, according to web metrics firm Net Applications.
Opera Software, one of the leaders in the European fight against Internet Explorer's bundling with the Windows operating system, also gained ground in December to claim a 2.4% share of the market.
Internet Explorer's market share fell 0.92% to a new low of 62.7%, which, although still representing a commanding lead, is 27.3% down on the browser's one time 90% market share.
In the second half of 2009, IE lost an average 0.94% market share a month.
