Firefox beta includes dozens of major features and improvements - by testing them early we'll be able to respond to your feedback for future versions of Firefox. Once you download Firefox, you're part of our beta program and will receive regular updates as more features launch.

1. Preview Features
Get a first look at the latest developer tools, security features and innovative HTML5 and other Web technologies.

2. Share Feedback
Test performance in an experimental environment, file bugs and help us determine what makes it to Beta.

3. Shape Firefox
Become part of a community of users, contributors and developers working to make the next Firefox our best yet.

Firefox Aurora is the equivalent of Chrome’s cutting-edge Dev, which means it’s definitely not for the average user. It’s effectively an alpha build of the next version of Firefox – more stable than the nightly builds produced for developers, but still a long way off the relative stability of beta versions, never mind a final release. Make sure your computer is backed up before installing this, but once done, you can install it and get an early glimpse into the future of the Firefox browser.

The Firefox browser is created by Mozilla, a non-profit organization whose mission is to promote openness, innovation and opportunity on the Web.

* Experience the newest innovations before they go to beta in an environment that’s not for the faint of heart
* Provide feedback on features and performance to help determine what makes the final release

What is Firefox?

We’re a global community
of thousands who sincerely believe in the power of technology to enrich people’s lives.

We’re a public benefit organization
dedicated not to making money but to improving the way people everywhere experience the Internet.

And we’re an open source software project
whose code has been used as a platform for some of the Internet’s most innovative projects.

Features:

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.

Improved Interface

We’re always looking for ways to make your browsing easier and more efficient.

Tabs on Top
Tabs are above the Awesome Bar to make it easier to focus on the content of the sites you visit.

Firefox Button (Windows and Linux)
All your menu items are now found in a single button for easy access.

Bookmark Button
Manage your bookmarks in a single button. Find your favorite links without getting bogged down!

Simplified Reload/Stop Button
Your Awesome Bar now features one easy button to stop loading pages or reload pages.

Home Button
The Home button has been moved to the right side of the search-field.

Tabs

Browse multiple sites at once, simply and easily. Each new site appears as a new tab
(not a new window) and can be accessed in one click.

App Tabs
Take sites you always keep open—like Web mail—off your tab bar and give them a permanent home in your browser.
