Apple Safari 4 beta on Windows Vista

Apple today announced the public beta of Safari 4 web browser for Mac and Windows PCs. The Nitro engine in Safari 4 runs JavaScript 4.2 times faster than Safari 3.

Innovative new features that make browsing more intuitive and enjoyable include Top Sites, for a stunning visual preview of frequently visited pages; Full History Search, to search through titles, web addresses and the complete text of recently viewed pages; Cover Flow, to easily flip through web history or bookmarks; and Tabs on Top, to make tabbed browsing easier and more intuitive.

“Apple created Safari to bring innovation, speed and open standards back into web browsers, and today it takes another big step forward,” said Philip Schiller, Apple’s senior vice president of Worldwide Product Marketing. “Safari 4 is the fastest and most efficient browser for Mac and Windows, with great integration of HTML 5 and CSS 3 web standards that enables the next generation of interactive web applications.”

Safari 4 is built on the world’s most advanced browser technologies including the new Nitro JavaScript engine that executes JavaScript up to 30 times faster than IE 7 and more than three times faster than Firefox 3. Safari quickly loads HTML web pages three times faster than IE 7 and almost three times faster than Firefox 3.

Safari 4 includes HTML 5 support for offline technologies so web-based applications can store information locally without an Internet connection, and is the first browser to support advanced CSS Effects that enable highly polished web graphics using reflections, gradients and precision masks. Safari 4 is the first browser to pass the Web Standards Project’s Acid3 test, which examines how well a browser adheres to CSS, JavaScript, XML and SVG web standards that are specifically designed for dynamic web applications.

Safari for Mac, Windows, iPhone and iPod touch are all built on Apple’s WebKit, the world’s fastest and most advanced browser engine. Apple developed WebKit as an open source project to create the world’s best browser engine and to advance the adoption of modern web standards. Most recently, WebKit led the introduction of HTML 5 and CSS 3 web standards and is known for its fast, modern code-base. The industry’s newest browsers are based on WebKit including Google Chrome, the Google Android browser, the Nokia Series 60 browser and Palm webOS.

Safari 4 is a public beta for both Mac OS X and Windows and is available immediately as a free download at .
