By one measure, the browser landscape was reshaped last month: According to data released today by StatCounter, which measures browser usage, Google's Chrome has taken over the No. 2 spot, sending Mozilla's Firefox to third place.

Microsoft's Internet Explorer is still king.

"We can look forward to a fascinating battle between Microsoft and Google as the pace of growth of Chrome suggests that it will become a real rival to Internet Explorer globally," Aodhan Cullen, StatCounter's CEO said in a statement. "Our stats measure actual browser usage, not downloads, so while Chrome has been highly effective in ensuring downloads our stats show that people are actually using it to access the web also."
