Born from Netscape’s 1998 open sourcing of the code base behind its Netscape Communicator internet suite, Mozilla Firefox currently holds approximately 22.48% of the world market for internet browsers as of April 2009. Version 1.0 was released on November 9, 2004 after a series of name changes, and within a year close to 100 million downloads of the browser technology had occurred.

The following two years saw upgrades to version 1.5 in November 2005 and 2.0 in October 2006. Firefox’s feature set includes tabbed browsing, an array of extensions, themes and add-ons to enable more functionality within the browser, as well as a variety of security measures that help the browser compete with Internet Explorer for customers.
