Mozilla Firefox is a fast, full-featured Web Browser that makes browsing more efficient than ever before. Firefox includes pop-up blocking; a tab-browsing; integrated Google searching; simplified privacy controls that let you Cover Your Tracks more effectively; a streamlined browser window that shows you more of the page than any other browser; and a number of additional features that work with you to help you get the most out of your time online.
Improved Tabbed Browsing
We love tabs as much as you do, so Firefox 2 will open new web pages in tabs
by default. Each of those tabs has its own close button, but don't worry - if you accidentally close a tab, just go to the History menu to bring it back from the list of 'Recently Closed Tabs.' You'll never be crunched for space anymore, either. When you have too many tabs open to comfortably fit in a single window, scroll arrows will appear on either side, and a button on the right side will always show you an easy-to-read list of all your open tabs.
Open Source, More Secure
At the heart of Firefox is an open source development process driven by thousands of passionate, experienced developers and security experts spread all over the world. Our openness and active community of experts helps to ensure our products are more secure and updated quickly, while also enabling us to take advantage of the best third party security scanning and evaluation tools to further bolster overall security.
Automated Update
Firefox's update system always checks to see if you're running the latest version, and notifies you when a security update is available. These security updates are small (usually 200KB - 700KB), giving you only what you need and making the security update quick to download and install. The automated update system provides updates for Firefox on Windows, Mac OS X, and Linux in over 40 different languages.
