Safari is a web browser developed by Apple Inc. and included with the Mac OS X and iOS operating systems. First released as a public beta on January 7, 2003 on the company's Mac OS X operating system, it became Apple's default browser beginning with Mac OS X v10.3 "Panther". Safari is also the native browser for iOS. A version of Safari for the Microsoft Windows operating system, first released on June 11, 2007, supports Windows XP, Windows Vista, and Windows 7. The latest stable release of the browser is 5.1, which is available as a free download for both Mac OS X and Microsoft Windows. As of 2011, Safari is the fourth most widely used browser in the US, following Internet Explorer, Mozilla Firefox, and Google Chrome, respectively.
Beginning with Safari 4, the address bar has been completely revamped:-
- The blue inline progress bar is replaced with a spinning bezel and a loading indicator attached to it.
- The button to add a bookmark is now attached to the address bar by default.
- The reload/stop button is now superimposed on the right end of the address bar.
These modifications make Safari on Mac OS X and Windows look more similar to Safari on iPhone than previous versions.
Safari 4 also includes the following new features:
- Completely passes the Acid3 standards test
- Cover Flow browsing for History and Bookmarks
- Improved developer tools, including Web Inspector, CSS element viewing, JavaScript debugger and profiler, offline table and database management with SQL support, and resource graphs
- Nitro JavaScript engine that executes JavaScript up to eight times faster than Internet Explorer 8 and more than four times faster than Firefox 3
- Native Windows look on Windows (Aero, Luna, Classic, etc., depending on OS and settings) with standard Windows font rendering and optional Apple font rendering
- Support for CSS image retouching effects
- Support for CSS Canvas
- Speculative loading, where Safari loads the documents, scripts, and style information that are required to view a web page ahead of time
- Support for HTML5
- Top Sites, which displays up to 24 thumbnails of a user's most frequently-visited pages on start up.
