To commemorate the three-year anniversary of the creation of the Mozilla Foundation on July 15, the open-source group announced that if a Firefox user persuades a friend to download the browser, both the user and the friend's names will be added to the source code of the next version of the browser,.
"Share Firefox with a friend. If your friend downloads Firefox before Sept. 15, you'll both be immortalized in Firefox 2," the Mozilla Foundation said in a statement.
Firefox has steadily gained market share since its launch in November 2004. According to recent statistics from Web analytics company OneStat, Firefox has a global usage share of 12.93 percent, and Microsoft's Internet Explorer's share has dropped to 83.05 percent of the market.
