Mozilla Firefox

Mozilla Firefox is a free Web browser developed and distributed by the Mozilla Foundation and hundreds of volunteers helped with the methods of development of free software / open source and free source code.

Firefox is a program originally derived from the Mozilla software (now known as SeaMonkey), but showing only the navigation functions of the latter. This cross-platform software is compatible with various versions of Microsoft Windows, Mac OS X and GNU / Linux.

It has been ported to other operating systems, which is made possible by the availability of its source code in three different free licenses at the same time (MPL, GPL and LGPL).

This software has enjoyed increasing success since its release, exceeding 1.2 billion downloads in January 2010.

Although this number does not reflect the actual number of software users, Firefox has quickly become the main competitor to Internet Explorer, the Microsoft Web browser.
