Net Applications Global Internet Usage Market Share study (say that ten times fast) tracked the release of the Firefox 3 release by the hour and monitored the well-promoted (yet poorly executed in my opinion due to downtime) Mozilla Download day and the results that followed in relation to usage market share for browsers. Net Applications states that Firefox made some "excellent gains in usage market share the last 2 months, which would imply a spoke in new users of FF3". See the chart below.
