Firefox 3, the recently released open source browser from Mozilla, has claimed that over 8 million copies of the software were downloaded on Download Day. The company stated early that their goal was to surpass the initial release of Firefox 2, at 1.6 million downloads in 24 hours, and hit 5 million downloads. The goal of the marketing campaign is to set a Guinness World Record for most downloaded software in a single day. A few days have passed and, barring the server downtime that plagued users for a few hours, the results look promising for Mozilla’s world record attempt. According to the official Mozilla blog, Firefox 3 easily cruised past 5 million user downloads. “We exceeded 8 million downloads in our 24 hour period,” the blog states. Downloads were tracked from 11:16am PDT on June 17th to 11:16am PDT on the following day.
