Firefox 3.0.

The browser provides virus, popup and spyware protection in a simple,
easy to use tabbed interface
The Firefox project (formerly Firebird, which was formerly Phoenix)
is a redesign of Mozilla's browser component, written using the
XUL user interface language and designed to be cross-platform.

Firefox is a small, fast and very easy to use browser that offers many
advantages over other web browsers, such as the ability to block pop-up
windows and the tabbed browsing.

Features of Mozilla Firefox:

· comprehensive
popup controls to keep unwanted advertising off your desktop;

· a tab browsing mode that lets you open several pages in a single window,
allowing you to load links in the background without leaving the page you're on;

· integrated search (powered by Google);

· industry leading accessibility with Find As You Type find links and page text by simply typing;

· simplified privacy controls that let you cover your tracks more effectively;

· a streamlined browser window that lets you see more of the page than any other browser while at the same time being more configurable;

· a large variety of free downloadable extensions and themes that add specific functionality and visual changes to the browser.
