Mozilla Firefox is a fast, full-featured browser for Windows that makes browsing more efficient than ever before. It offers a complete set of features to give you a truly user-friendly experience.Firefox has quickly become the reference in alternative web browsers.

Here are its main features:

Popup blocking

Stop annoying popup ads in their tracks with Firefox's built in popup blocker

Tabbed browsing

View more than one web page in a single window with this time saving feature. Open links in the background so that they're ready for viewing when you're ready to read them.

Privacy and security

Built with your security in mind, Firefox keeps your computer safe from malicious spyware by not loading harmful ActiveX controls. A comprehensive set of privacy tools keep your online activity your business.

Smarter search

Google Search is built right into the toolbar, and there is a plethora of other search tools including Smart Keywords (type "dict " in the Location bar), and the new Find bar (which finds text as you type without covering up anything).

Live bookmarks

RSS integration lets you read the latest news headlines and read updates to your favorite sites that are syndicated.

Hassle-free downloading

Files you download are automatically saved to your Desktop so they're easy to find. Fewer prompts mean files download quicker.

Fits like a glove

Simple and intuitive, yet fully featured, Firefox has all the functions you're used to - Bookmarks, History, Full Screen, Text Zooming to make pages with small text easier to read, etc.

S, M, L or XL—it's your choice

Firefox is the most customizable browser on the planet. Customize your toolbars to add additional buttons, install new Extensions that add new features, add new Themes to browse with style, and use the adaptive search system to allow you to search an infinite number of engines. Firefox is as big or small as you want.

Setup's a snap

At only 4.7MB (Windows), Firefox takes just a few minutes to download over a slow connection and seconds over a fast connection. The installer gets you set up quickly, and the new Easy Transition system imports all of your settings - Favorites, passwords and other data from Internet Explorer and other browsers - so you can start surfing right away.

A developer's best friend

Firefox comes with a standard set of developer tools including a powerful JavaScript and CSS error/warning console, and an optional Document Inspector that gives detailed insight about your pages.

"Best browser of all."
