Tuesday, Apple Incorporated launched its new browser Safari 4 for both the Mac OS X and the Windows operating system, which promises to be much faster than other browsers, with 150 new features having been added to it.

The Safari 4 beta browser has a new user interface, which much resembles that of Google’s browser Chrome for computers running on the Windows XP operating system.

The browser features a Top Sites tool, which can aggregate as much as twenty thumbnails at a time, between which users can switch by clicking the Edit button.

The tool is similar to Google Chrome's „Most Recent” page and Opera's „Speed Dial,” and just like them, it allows users to arrange the thumbnails according to their preferences, while by default, the top sites are displayed based on browsing behavior such as preferred websites and usage statistics.

Apple’s new browser also comes with the Cover Flow feature, which allows flipping between the website histories of visited pages and also enables the Browsing History and Bookmarks to be viewed via Cover Flow with a thumbnail or entire page review.

In addition, the company is now hailing a new JavaScript engine Nitro that can enhance JavaScript handling, which makes the Safari 4 browser better than Internet Explorer 7 and Firefox 3.0.6 browsers in this respect.

According to the company, Safari 4 runs 30 times faster than IE7 and three times faster than Firefox 3.0.6, Apple having based its conclusions on the SunSpider JavaScript Benchmark and iBench tests, which Microsoft’s and Mozilla’s browsers have yet to pass.
