According to Netapplications.com, Firefox's share of the browser market climbed to 8.71% in June from 8% in May, while IE's share shrank to 86.56% from 87.23%. Netapplications, which monitors 40,000 Web sites, said Firefox has been adding 0.5% to 1% of market share a month since the beginning of the year. As Firefox gets close to the 10% level, you have to ask whether its growth is close to being fully realized - now that all the geeks, bleeding-edge and leading-edge folks are on board - or whether Firefox is poised to hit the mainstream, and on its way to 20% to 25% of the browser market. It will be interesting to see whether IE7 with its tabs and increased anti-virus features can stem the tide. According to the Mozilla Web site, Firefox has been downloaded 64 million times.
