"With over 350 million users of its open source Firefox
Web browser worldwide, Mozilla is a group that has some insight
into the state of the Internet, topic explored in some depth in its
new report issued this week.
"The Q1 2010 Mozilla State of the Internet report sheds light on
both the adoption and usage of Firefox globally. The data in the
report is a combination of both Mozilla's own stats as well as
leveraging data from StatCounter, Quantcast, Net Applications, and
Gemius for global market share. Averaging all the reported global
browser share data sets, Mozilla has determined that Firefox has a
global market share of 30 percent."
