Firefox is an open-source web browser whose advanced security features and intuitive design have led to its growing popularity. Firefox is a free alternative to other web browsers such as Microsoft's Internet Explorer, and is available for download by anyone, anywhere. The fact that it is open-source allows for an infinite number of copies of the software to be legally installed on any number of machines. Firefox boasts integrated security features such as automatically disallowing pop-ups and spyware, and built-in phishing protection to spot suspected Web forgeries. Firefox features a customizable interface, tabbed browsing windows to reduce clutter, an interactive Find feature, and a wide variety of plug-ins to do everything from enable audio screen reading to interpreting commands based on the movements of your mouse.
If you are upgrading from a previous version of Firefox, the previous installation must be completely uninstalled before beginning the setup process.
