Mozilla Firefox 9
Fast/Secure internet browser 
Everybody uses the Web differently, so why should your browser be exactly like the next person’s? Firefox has more than 6,000 add-ons to help you customize it to your exact needs, plus thousands of Personas to instantly change the way it looks.
Awesome Bar
Get to your favorite sites quickly – even if you don’t remember the URLs. Type your term into the location bar (aka the Awesome Bar) and the autocomplete function will include possible matches from your browsing history, bookmarked sites and open tabs.
The Awesome Bar learns as you use it—over time, it adapts to your preferences and offers better-fitting matches. We’ve tweaked it to give you greater control over the results (including privacy settings) and increased performance so you find what you need even faster.
Importing favorites and other data from Internet Explorer
Firefox lets you import settings and data from Internet Explorer, saving you from having to configure many things yourself. This article gives you step-by-step instructions for getting it done.
Secure Your Personal Info
We’ve packed Firefox with highly advanced security features to keep you safe while you browse. And, as a non-profit organization, protecting your privacy by keeping you in control over your personal information is a key part of our mission.
How do I stop websites from tracking me?
Most major websites track their visitors' behavior and then sell or provide that information to other companies (like advertisers). Firefox has a Do-not-track feature that lets you tell websites you don't want your browsing behavior tracked. This article explains what tracking is, how the Do-not-track feature works and how to turn it on.
Explore The Cutting Edge
As part of our mission to make the Web better, Firefox supports the latest and greatest technology like HTML5 to make sure you can enjoy the most innovative and advanced sites out there. Be sure to check out our demo gallery for some examples of what the modern Web can do.
