Safari is a web browser developed by Apple Inc. and included in Mac OS X. It was first released as a public beta on January 7, 2003,[1] and is the default browser in Mac OS X v10.3 and later. It is also the native browser on the Apple iPhone and iPod touch. A beta version for Microsoft Windows was released for the first time on June 11 2007 with support for Windows XP and Windows Vista,[2], with a release version for Windows following on March 18, 2008. Safari has also been run unofficially on Linux under Wine, but the graphical user interface (GUI) and web graphics do not render properly.[3]

Since the release of Safari, its usage share has been climbing. For the month of February 2008, TheCounter.com reports a a usage share of 3.34% for Safari;[4] while Net Applications records a usage share of 4.61% in April 2007 and 5.70% in February 2008.[5]

Features

Safari offers most features common to modern web browsers. In addition, some of these features are implemented in distinctive ways, while it also includes some unique to the browser:

  • A tabbed-browsing interface that allows dragging tabs to reorder them, move them between windows or create new windows.
  • A bookmark management scheme reminiscent of the iTunes jukebox software.
  • A resizable web-search box in the toolbar. This uses Google on the Mac and either Google or Yahoo! on Windows.
  • Pop-up ad blocking.
  • As-you-type text search.
  • Spell-checking for all text entry fields.
  • Expandable text entry boxes, which can be resized by the user to make entering long texts easier.
  • Automatic filling in of web forms.
  • Built-in password management via Keychain.
  • Functionality for subscribing to and reading web feeds.
  • Quartz-style font-smoothing even on Windows.
  • Integration of Apple's QuickTime multimedia technology.
  • Support for user-specified style sheets.
  • The Web Inspector, a DOM Inspector-like utility that lets users and developers browse the Document Object Model of a web page.[6]
  • A high level of standards compliance through its use of the WebKit framework, including partial, preliminary support for CSS3 and HTML 5.

CSS support

Safari features full support for Cascading Style Sheets (CSS), including partial support of CSS3.[7] Safari 3 supports several experimental properties like text-shadow, text-stroke, box-shadow, border-image, multiple backgrounds for each element, resizeable elements, rgba() and the CSS3 pseudo-element :first-of-type.

History and development

Until 1997, Apple Macintosh computers had shipped with Netscape Navigator only, competing with Internet Explorer 2.x and 3. Microsoft's Internet Explorer for Mac was subsequently included as the default web browser as part of the five year agreement between Apple and Microsoft. However, Netscape Navigator continued to be included. Microsoft released three major versions of Internet Explorer for Mac that were bundled with the OS, with the last one, Internet Explorer 5 being released on March 27, 2000.

On January 7, 2003, Steve Jobs announced that Apple had developed their own web browser based on KHTML rendering engine, called Safari.[8] They released the first beta version that day and a number of official and unofficial beta versions followed, until version 1.0 was released on June 23, 2003. Available as a separate download initially, it was included with the Mac OS X v10.3 release on October 24, 2003, as the default browser, with Internet Explorer for Mac included only as an alternative browser. Since the release of Mac OS X v10.4 in April 29, 2005, Safari is the only web browser included with the operating system.

Safari uses Apple's WebKit for rendering web pages and running JavaScript. WebKit consists of WebCore (based on Konqueror's KHTML engine) and JavaScriptCore (based on KDE's JavaScript engine named KJS). Like KHTML and KJS, WebCore and JavaScriptCore are free software and are released under the terms of the GNU Lesser General Public License. Some Apple improvements to the KHTML code are merged back into the Konqueror project. Apple also releases additional code under an open source 2-clause BSD-like license.

In June 2005, after some criticism from KHTML developers over lack of access to change logs, Apple moved the development source code and bug tracking of WebCore and JavaScriptCore to OpenDarwin.org. WebKit itself was also released as open source. The source code for non-renderer aspects of the browser, such as its GUI elements, remains proprietary.

Version 2.0 of Safari, was released on April 29, 2005 and runs only on Mac OS X 10.4.x (Tiger) or later. It includes a built-in RSS and Atom reader. Other features include Private Browsing (a mode in which no record of information about the user's web activity is retained), the ability to archive (using the proprietary .webarchive format) and e-mail web pages, the ability to search bookmarks, and a reported 1.8 times speed boost over version 1.2.4.

In April 2005, Dave Hyatt, one of the Safari developers at Apple, documented his progress fixing bugs in Safari to get it to pass the Acid2 test. On April 27, 2005, he announced that his development version of Safari now passed the test, making it the first web browser to do so.[9] The changes were not initially available to end-users unless they downloaded and compiled the WebKit source code themselves or ran one of the nightly automated builds available at opendarwin.org.[10] However on October 31, 2005, Apple released version 2.0.2 of Safari that included the Acid2 bug fixes.

On January 9 2007, Steve Jobs formally announced Apple's iPhone, which uses the Safari browser.

At the 2007 Worldwide Developers Conference, Steve Jobs announced Safari 3 for Microsoft Windows XP and Windows Vista. The Safari beta version for Windows had several known bugs[11] and a zero day exploit that allows remote execution, upon its initial beta release on June 11, 2007, in version 3.0.[12] The addressed bugs were then corrected by Apple three days later on June 14, 2007, in version 3.0.1 on Windows. On June 22, 2007, Apple released Safari 3.0.2 to address some bugs, performance issues and other security issues. Safari 3.0.2 for Windows handles some fonts that are missing in the browser but already installed on your computer, such as Tahoma, Trebuchet MS, and others. There is also a guide that allows the software to run under Linux with Wine.[13] The final release Windows version, 3.1 (525.13), was offered as a free download on March 18, 2008.

At the announcement, Steve Jobs claimed that Safari is the fastest browser and, to prove this, he ran a benchmark, based on the iBench browser test suite, live at the show. External measurement of Hypertext Transfer Protocol (HTTP) load times suggested that Safari is the fastest browser on the Windows platform in terms of initial data loading over the Internet, but is tied with Internet Explorer 7 and Firefox when comparing loading from caches[14].

Criticism

Distribution through Apple Software Update

Apple Inc. has been criticized for using Apple Software Update, which is bundled with QuickTime and iTunes in Microsoft Windows, to promote Safari to Windows users. When Safari 3.1 is not detected in a user's machine, the updating software, by default, automatically selects the browser for installation. John Lilly, CEO of Mozilla, stated that Apple's use of its updating software to promote its other products is "a bad practice and should stop." He argued that the practice "borders on malware distribution practices" and "undermines the trust that [software companies are] all trying to build with users."[15] Apple has responded to Lilly's statement, saying that the company is only trying to ensure users have the latest updates to Safari.[15] This statement can be misleading in the fact that Safari 3.1 appears as an update, even when Safari is not installed on the computer.

Version history
