Internet Explorer is still the king with a marketshare of 65 percent and the rest of the market is split between small players like Opera (3.3%), Safari (2.3%), Netscape (0.5%) and others.
Another interesting thing the report unveils is that Firefox usage is much higher in the weekends, during the week it's 28.3% but during the weekend it jumps to 30.1%. This indicates that a lot of people use Firefox at home but are somewhat forced to use Internet Explorer at work.
Firefox usage is the highest in Oceania and Europe and trails behind a bit in Asia and Africa. Usage of Firefox increased in almost every continent in March, only in North America it dropped a little bit from 21.9% to 21.7%
Firefox usage per continent:
Oceania: 31.2% Europe: 28.8% North America: 21.7% South America: 21.3% Africa: 17.9% Asia: 17.2%
