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.

Here are some key features of "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.

Requirements:

· Pentium 233 MHz (Recommended: Pentium 500MHz or greater)
· 64 MB RAM (Recommended: 128 MB RAM or greater)
· 52 MB hard drive space

Change Log:

· Tabs are now on top by default on Windows only - OSX and Linux will be changing when the theme has been modified to support the change.
· On Windows Vista and Windows 7 the menu bar has been replaced with the Firefox button.
· You can search for and switch to already open tabs in the Smart Location Bar
· New Addons Manager and extension management API (UI will be changed before final release)
· Significant API improvements are available for JS-ctypes, a foreign function interface for extensions.
· The stop and reload buttons have been merged into a single button on Windows, Mac and Linux.
· The Bookmarks Toolbar has been replaced with a Bookmarks Button by default (you can switch it back if you'd like).
· Crash protection for Windows, Linux, and Mac when there is a crash in the Adobe Flash, Apple Quicktime or Microsoft Silverlight plugins.
· CSS Transitions are partially supported.
· Full WebGL support is included but disabled by default at this time.
