Newest Update to Firefox 4 Beta

· Firefox, Mozilla News

The latest update of Firefox 4 Beta is now available for download and testing in more than 30 languages, adding 10 new languages. This update includes multi-touch support for Windows 7 and new JavaScript values to experience faster and smoother graphics. We also have vital feedback from our testers that we will incorporate into future updates.

More details on the cool new features for Web developers in this Firefox 4 Beta update:

Multi-touch
Firefox 4 Beta now has multi-touch support for Windows 7 to enable people to
interact with Web content with their hands naturally. Developers can use multi-touch capabilities to leverage touch-enabled devices and provide people with an intuitive and fun browsing experience. For more details, see the blog posts by Paul Rouget and Felipe Gomes.

New JavaScript Values
Changes to the C++ representation of JavaScript enable Firefox to execute heavy, numeric code more efficiently. This sort of code is used to produce smooth, streamlined graphics in modern Web applications. For more details, see Rob Sayre’s blog post.

Firefox 4 Beta includes a Feedback Add-on with Mozilla Labs Test Pilot, which will ask you to take part in anonymous studies. You can choose to opt-out of any or all studies and manage your settings in the Feedback button. The feedback is used to help us improve future Firefox Beta releases. See Mike Beltzner’s blog post for more details.

The Feedback tool has been a great success, and our half-million testers submit approximately 3,500 pieces of feedback every day. Test Pilot recently conducted a survey of Firefox 4 Beta testers to help us better understand the dedicated testers who have been giving us this fantastic feedback. We discovered that our beta users are primarily men who use the Web between two and six hours each day, mostly for entertainment and communication. This doesn’t come as a surprise to us, but it also isn’t a great representation of Internet users. We need your help! If you’re enjoying using the Firefox 4 Beta, tell your friends, get them set up and don’t forget to point out the Feedback button.

Firefox 4 Beta testers will receive automatic updates, so stay tuned for the next release in the coming weeks.
