'''Safari''' is a [[Software:WebKit|WebKit]]-based partially open source [[Graphical user interface|graphical]] [[Software:Web browser|web browser]] developed by [[Company:Apple Inc.|Apple]]. It first appeared as part of [[Software:Mac OS X Panther|Mac OS X Panther]] on the Mac in 2003; later, a mobile version was introduced as part of [[Software:IPhone OS 1|iPhone OS 1]] on the [[Engineering:IPhone|iPhone]] and iPod touch in 2007. It is currently supported on [[Software:IOS|iOS]] and [[Software:MacOS|macOS]]. A [[Software:Microsoft Windows|Windows]] version was available from 2007 to 2012.<ref name="safari-on-windows" />

It was among many graphical browsers running [[Company:Google|Google]]'s Safe Browsing. A pop-up blocker is enabled with Safari by default; there is also an optional Javascript blocker extension togglable via the system preferences. Data collected from Safari are stored externally on the system's default syncing platform called [[Company:ICloud|iCloud]], rather than on the browser itself. The default [[Search engine|search engine]] is [[Software:Google Search|Google]], other optional search engine includes [[Software:Microsoft Bing|Bing]], [[Company:Yahoo!|Yahoo]], and [[Software:DuckDuckGo|DuckDuckGo]].<ref>{{cite web|date=2021-02-02|author=Aleksander Hougen|url=https://www.cloudwards.net/safari-review/|title=Safari Review|publisher=Cloudwards|accessdate=2021-05-18}}</ref> In 2005, Apple open-sourced Safari's source code, beforehand only its WebCore and JavaScript Core libraries were publicly accessible, <ref>{{cite web|date=2016-01-07|author=Daniel Eran Dilger|url=https://appleinsider.com/articles/16/01/07/apples-safari-browser-turns-13-years-old-today|title=Apple's Safari browser turns 13 years old today|publisher=AppleInsider|accessdate=2021-05-17}}</ref> but it contains proprietary components.<ref>{{Cite web|last=Hodge|first=Rae|title=Browser privacy boost: Here are the settings to change in Chrome, Firefox, Safari, Edge and Brave|url=https://www.cnet.com/how-to/browser-privacy-settings-change-chrome-firefox-safari-edge-and-brave/|access-date=2021-05-20|website=CNET|language=en}}</ref>

Safari 14, released on November 12, 2020, is the latest version for Mac as part of [[Software:MacOS Big Sur|macOS Big Sur]]. Apple claims that it is up to 50 percent faster than [[Software:Google Chrome|Google Chrome]] while consuming less battery power than other standard web browsers.<ref>{{cite web|date=2020-11-09|author=Roman Loyola|url=https://www.macworld.com/article/234809/macos-big-sur-11-whats-new-in-safari-14.html|title=macOS Big Sur 11: What’s new in Safari 14|publisher=Macworld|accessdate=2021-05-18}}</ref> The latest version for [[Software:IOS|iOS]] was released on September 16, 2020, running [[Software:IOS 14|iOS 14]].

As of April 2021, Safari ranked as the second most popular web browser after Chrome, with a market share of 19.40% worldwide and 38.56% in the US.<ref>{{cite web|date=2021-04-30|author=Oberlo staff|url=https://www.oberlo.com/statistics/browser-market-share|title=Most popular web browsers in 2021|publisher=Oberlo|accessdate=2021-05-19}}</ref>

== History and development ==
[[File:Internet Explorer 10+11 computer icon.png|thumb|upright=0.6|left|The Internet Explorer]]
Before 1997, Apple's [[Engineering:Macintosh|Macintosh]] computers were shipped exclusively with the [[Software:Netscape Navigator|Netscape Navigator]] and [[Software:Cyberdog|Cyberdog]] web browsers. [[Software:Internet Explorer for Mac|Internet Explorer for Mac]] was later introduced as the default web browser since [[Software:Mac OS 8|Mac OS 8.1]] as part of a five-year agreement between Apple and its rival, Microsoft.<ref name="apple-macos8.1">{{cite web|url=http://docs.info.apple.com/article.html?artnum=30345#English|title=Mac OS 8.1 Update Document and Software|date=August 14, 2003|publisher=Apple Inc.|access-date=June 10, 2009|archive-url=https://web.archive.org/web/20101204003221/http://docs.info.apple.com/article.html?artnum=30345#English|archive-date=December 4, 2010|url-status=dead}}</ref> During that time, Microsoft announced three major versions of Internet Explorer for Mac that were used by Mac OS 8 and [[Software:Mac OS 9|Mac OS 9]], though Apple continued to support Netscape Navigator as an alternative. Microsoft ultimately released a Mac OS X edition of Internet Explorer for Mac, which was bundled as the default browser in all Mac OS X releases from Mac OS X DP4<ref name="apple-macosxdp4">{{cite web|url=https://www.apple.com/newsroom/2000/05/15Apple-Releases-Mac-OS-X-Developer-Preview-4-with-Final-API-Specs/|title=Apple Releases Mac OS X Developer Preview 4 with Final API Specs|date=May 15, 2000|publisher=Apple Inc.|access-date=March 13, 2018}}</ref> to Mac OS X v10.2.<ref name="adc-java131">{{cite web|url=https://developer.apple.com/releasenotes/Java/Java131MOSX10.2RN/applets/chapter_2_section_2.html|title=Java 1.3.1 for Mac OS X version 10.2 Release Notes|date=July 2002|work=developer.apple.com|publisher=Apple Inc.|access-date=June 10, 2009}}</ref>

Before the name Safari being used, a couple of others were drafted, including 'Freedom.' For over a year internally, the browser was widely known as 'Alexander'; that name was used as a string in the code and resources. Apple's development team also casually referred to it as 'iBrowse' prior to Safari being the chosen name.<ref>{{Cite web|title=Apple's Former Safari Chief Don Melton Reflects on Steve Jobs|url=https://www.macrumors.com/2014/04/11/don-melton-steve-jobs/|access-date=March 26, 2021|website=MacRumors|language=en}}</ref><ref>{{Cite web|url=https://donmelton.com/2012/12/19/when-i-first-heard-the-name-safari/|title=When I first heard the name “Safari”|first=Don|last=Melton|date=December 19, 2012|access-date=March 26, 2021|website=donmelton.com}}</ref>

=== Safari 1 ===
On January 7, 2003, at Macworld San Francisco, [[Biography:Steve Jobs|Steve Jobs]] announced that Apple had developed its own web browser, called Safari.<ref>{{Cite web|last=Keizer|first=Gregg|date=2013-01-08|title=Apple's Safari turns 10|url=https://www.computerworld.com/article/2494515/apple-s-safari-turns-10.html|url-status=live|access-date=2021-05-20|website=Computerworld|language=en}}</ref> It was based on Apple's internal [[Software:Fork (software development)|fork]] of the [[Software:KHTML|KHTML]] [[Software:Browser engine|rendering engine]], called [[Software:WebKit|WebKit]].<ref>{{cite web |first=Andreas |last=Pour |title=Apple Announces New "Safari" Browser |url=http://dot.kde.org/1041971213/ |work=KDE Dot News |date=January 7, 2003 |access-date=January 4, 2006}}</ref> The company released the first beta version, available exclusively for Mac OS X. Later that day, several official and unofficial beta versions followed up until version 1.0 was released on June 23, 2003.<ref>{{cite web| url=http://support.apple.com/kb/HT2964| title=Safari 1.0 for Mac OS X: Information and download| website=apple.com| access-date=September 24, 2017}}</ref>

On Mac OS X v10.3, Safari was pre-installed as the system's default browser, rather than requiring a separate download, as was the case with previous Mac OS X versions. Safari's predecessor, the Internet Explorer for Mac, was included in 10.3 as an alternative.<ref>{{Cite press release|author=Apple|url=https://www.apple.com/newsroom/2003/10/08Apple-Announces-Mac-OS-X-Panther/|title=Apple Announces Mac OS X “Panther”|publisher=Apple Newsroom|accessdate=2021-05-17}}</ref>

=== Safari 2 ===
In April 2005, Dave Hyatt, a Safari developer, fixed several [[Software bug|bugs]] in Safari, thereby enabling it to pass the [[Acid2]] test developed by the [[Company:Web Standards Project|Web Standards Project]].<ref>{{cite web|url=http://weblogs.mozillazine.org/hyatt/index.html|title=Surfin' Safari|first=Dave|last=Hyatt|date=April 2005|archive-url=https://web.archive.org/web/20050507043322/http://weblogs.mozillazine.org/hyatt/archives/2005_04.html|archive-date=May 5, 2005}}</ref> 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.<ref name="acid2">{{cite web|url=http://weblogs.mozillazine.org/hyatt/index.html#008042|title=Surfin' Safari|first=Dave|last=Hyatt|at=Safari Passes the Acid2 Test (Updated)|date=April 27, 2005|archive-url=https://web.archive.org/web/20050507043322/http://weblogs.mozillazine.org/hyatt/archives/2005_04.html#008042|archive-date=May 5, 2005}}</ref>

Safari 2.0 was released on April 29, 2005, as the only web browser Mac OS X 10.4 offer by default. Apple touted this version as it was capable of running a 1.8x speed boost compared to version 1.2.4, but it did not yet feature the Acid2 bug fixes. These major changes were initially unavailable for end-users unless they installed and compiled the WebKit [[Source code|source code]] or ran one of the nightly automated builds available at OpenDarwin.org. Apple eventually released version 2.0.2 of Safari, which included the modifications required to pass Acid2, on October 31, 2005.<ref name="nightly builds">{{cite web |first=Dave |last=Hyatt |title=Nightly Builds |url=http://webkit.org/blog/29/nightly-builds/ |work=Surfin' Safari |publisher=OpenDarwin.org |date=October 12, 2005 |access-date=October 29, 2006}}</ref>

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 is for non-renderer aspects of the browser, such as its [[Graphical user interface|GUI]] elements and the remaining proprietary.<ref>{{cite web|date=2003-10-26|author=OpenSourceApple|url=https://opensource.apple.com/source/JavaScriptCore/JavaScriptCore-5523.10.3/ChangeLog|title=Safari JavaScriptCore-5523.10.3/ChangeLog|publisher=OpenSourceApple|accessdate=2021-05-17}}</ref>

The final stable version of Safari 2, Safari 2.0.4, was updated on January 10, 2006, for Mac OS X. It was only available as part of Mac OS X Update 10.4.4. This version delivers layout and CPU usage issues, among other improvements. Safari 2.0.4 was the last version released exclusively with Mac OS X.<ref>{{cite web|url=http://support.apple.com/kb/HT2343|title=About the Mac OS X 10.4.4 Update (Delta)|access-date=September 12, 2015}}</ref>

=== Safari 3 ===
[[File:SilverStripe admin 3.1.png|thumb|Safari 3.1]]
On January 9, 2007, at Macworld SF, Steve Jobs announced the [[Engineering:IPhone|iPhone]]. The device's [[Operating system|operating system]], initially called iPhone OS,  but was later renamed to [[Software:IOS|iOS]] made uses of a mobile version of the Safari browser capable of displaying full, desktop-class websites.<ref>{{cite web|url=https://www.apple.com/pr/library/2007/01/09iphone.html|title=Apple - Press Info - Apple Reinvents the Phone with iPhone|access-date=September 12, 2015}}</ref>

At WWDC 2007, Steve Jobs announced Safari 3 for Mac OS X 10.5, Windows XP, and Windows Vista. During the announcement, he ran a benchmark based on the iBench browser test suite comparing the most popular Windows browsers,<ref>{{cite web |first=Mark |last=Wilton-Jones |title=Is Safari faster? |url=http://www.howtocreate.co.uk/safaribenchmarks.html |access-date=June 12, 2008}}</ref> hence claiming that Safari has the fastest browser performance. His claim was later reviewed by a third-party test of [[Hypertext Transfer Protocol|HTTP]] load times, they verified that Safari 3 was indeed the fastest browser on the Windows platform in terms of initial data loading over the Internet though it was only negligibly faster than [[Software:Internet Explorer 7|Internet Explorer 7]] and [[Software:Mozilla Firefox|Mozilla Firefox]] when it came io static content from the local cache.<ref>{{cite web |first=Michae |last=Czeiszperger |title=Safari 3 Windows Performance Analysis |url=http://www.webperformanceinc.com/library/reports/Safari%20Benchmarks/index.html |publisher=Web Performance |date=October 20, 2007 |access-date=July 24, 2007}}</ref>

The initial Safari 3 beta version for Windows, released on the same day as its announcement at WWDC 2007, contains several  bugs<ref>{{cite web |first=David |last=Maynor |title=Niiiice.. |url=http://erratasec.blogspot.com/2007/06/niiiice.html |publisher=Errata Security |date=June 11, 2007 |access-date=June 12, 2008}}</ref> and a zero day exploit that allowed remote execution.<ref>{{cite web |first=Thor |last=Larholm |title=Safari for Windows, 0day exploit in 2 hours |url=http://larholm.com/2007/06/12/safari-for-windows-0day-exploit-in-2-hours/ |date=June 12, 2007 |access-date=June 12, 2008}}</ref> The addressed bugs were then fixed by Apple three days later on June 14, 2007, in version 3.0.1 for 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 missing in the browser but already installed on Windows computers, such as Tahoma, Trebuchet MS, and others.<ref>{{cite web|date=2016|author=Phyliss Pereira|url=http://psulibrary.palawan.edu.ph/wtbooks/resources/pdf/9781280251702.pdf|title=Encyclopedia of Web Browsers|publisher=Learning Press|accessdate=2021-05-17}}</ref>

The iPhone was formally released on June 29, 2007, with a version of Safari based on the same WebKit rendering engine as the desktop version but with a modified feature set better suited for a mobile device. The version number of Safari as reported in its [[User agent|user agent string]] is 3.0, was in line with the contemporary desktop versions of Safari.<ref>{{cite web|url=http://the.taoofmac.com/space/com/Apple/iPhone/Safari|title=Mobile Safari|author=Rui Carmo|access-date=September 12, 2015|date=June 30, 2007}}</ref>

The first stable, non-beta release of Safari for Windows, Safari 3.1, was offered as a free download on March 18, 2008. In June 2008, Apple released version 3.1.2,<ref>{{cite web|url=http://support.apple.com/kb/HT2092|title=About the security content of Safari 3.1.2 for Windows|access-date=September 12, 2015}}</ref><ref>{{cite web|url=https://www.computerworld.com/article/2534403/security0/apple-does-about-face--fixes-safari-s--carpet-bomb--bug.html#tk.drr_mlt|title=Apple does about-face, fixes Safari's 'carpet bomb' bug|last= Keizer|first=Gregg|date=June 19, 2008|website=ComputerWorld}}</ref> addressing a security vulnerability in the Windows version where visiting a malicious web site could force a download of executable files and execute them on the user's desktop.<ref>{{cite web |title=Microsoft Security Advisory 953818 |url=https://docs.microsoft.com/en-us/security-updates/securityadvisories/2008/953818 |publisher=Microsoft |access-date=January 19, 2019}}</ref>

Safari 3.2, released on November 13, 2008, introduced [[Software:Anti-phishing software|anti-phishing]] features using [[Software:Google Safe Browsing|Google Safe Browsing]] and [[Extended Validation Certificate]] support.<ref>{{cite web|date=2008-10-24|author=MacJournals staff|url=https://www.macworld.com/article/193605/safari-safe-browsing.html|title=Inside Safari 3.2’s anti-phishing features|publisher=Macworld|accessdate=2021-05-17}}</ref> The final version of Safari 3 is 3.2.3, released on May 12, 2009.<ref>{{cite web|date=2009-05-12|author=Peter Cohen|url=https://www.macworld.com/article/196655/safari323.html|title=Safari 3.2.3 improves security|publisher=Macworld|accessdate=2021-05-17}}</ref>

=== Safari 4 ===
On June 2, 2008, the WebKit development team announced SquirrelFish,<ref>{{cite web |first=Geoffrey |last=Garen |title=Announcing SquirrelFish |url=http://webkit.org/blog/189/announcing-squirrelfish/ |date=June 2, 2008 |access-date=June 11, 2008}}</ref> a new [[JavaScript engine]] that vastly improves Safari's speed at interpreting scripts.<ref>{{cite web |first=Vygantas |last=Lipskas |title=Apple Safari 4 |url=http://www.favbrowser.com/apple-safari-4/ |date=June 11, 2008 |access-date=June 11, 2008}}</ref> The engine is one of the new features in Safari 4, released to developers on June 11, 2008. The new JavaScript engine quickly evolved into SquirrelFish Extreme, featuring even further improved performance over SquirrelFish,<ref>{{cite web|url=http://webkit.org/blog/214/introducing-squirrelfish-extreme/|title=Surfin' Safari|access-date=September 12, 2015|date=September 19, 2008}}</ref> and was eventually marketed as Nitro. A public beta of Safari 4 was released on February 24, 2009, with new features such as the Top Sites tool (similar to [[Software:Opera (web browser)|Opera]]'s [[Features of the Opera web browser#Speed Dial|Speed Dial]] feature), which displays the user's most visited sites on a 3D wall.<ref>{{cite web|url=https://arstechnica.com/apple/news/2009/02/hands-on-safari-4-beta-fast-mixes-polish-rough-ui-edges.ars|title=Hands on: Safari 4 beta fast, mixes polish, rough UI edges|work=Ars Technica|access-date=September 12, 2015|date=February 24, 2009}}</ref> [[Software:Cover Flow|Cover Flow]], a feature of Mac OS X and [[Software:ITunes|iTunes]], was also implemented in Safari. In the public beta versions, [[Tab (GUI)|tabs]] were placed in the title bar of the window, similar to [[Software:Google Chrome|Google Chrome]]. The tab bar was moved back to its original location, below the URL bar, in the final release.<ref>{{cite web|url=http://theappleblog.com/2009/06/08/apple-releases-safari-4/|title=Apple Releases Safari 4|last=Dempsey|first=James|date=June 9, 2009|work=TheAppleBlog|publisher=The GigaOM Network|access-date=June 9, 2009}}</ref> The Windows version adopted a native Windows [[Theme (computing)|theme]], rather than the previously employed Mac OS X-style interface. Also, Apple removed the blue progress bar located in the address bar (later reinstated in Safari 5). Safari 4.0.1 was released for Mac on June 17, 2009, and fixed problems with Faces in [[Software:IPhoto|iPhoto]] '09. Safari 4 in Mac OS X v10.6 "Snow Leopard" has 64-bit support, which can make [[JavaScript]] loading up to 50% faster. It also has built-in crash resistance unique to Snow Leopard; crash resistance will keep the browser intact if a plug-in like Flash player crashes, such that the other tabs or windows will be unaffected.<ref>{{cite web|url=https://www.apple.com/macosx/what-is-macosx/safari.html|title=Apple - Mac OS X - What is Mac OS X - Safari|website=Apple|url-status=dead|archive-url=https://web.archive.org/web/20110521134811/http://www.apple.com/macosx/what-is-macosx/safari.html|archive-date=May 21, 2011}}</ref> Safari 4.0.4, released on November 11, 2009, for both OS X and Windows, further improves JavaScript performance.<ref>{{cite web|url=http://support.apple.com/kb/DL877|title=Apple - Support - Downloads|access-date=September 12, 2015}}</ref>

==== Safari 4 features ====
[[File:Macosskinwin.PNG|thumb|left|Wikipedia on Safari 4]]
Safari 4 was the first version that completely passed the [[Acid3]] standard test.

On Windows, rather than providing a Mac OS X-like interface, Safari adopted the native Windows look, ([[Windows Aero|Aero]], Luna, Classic, etc., depending on OS and settings), using standard Windows fonts.<ref name="apple.com2">{{cite web|title=What's new in Safari - See the new features available in Safari 4 for Mac and PC|url=https://www.apple.com/safari/whats-new.html|website=Apple|archive-url=https://web.archive.org/web/20090627155532/http://www.apple.com/safari/whats-new.html|archive-date=June 27, 2009}}</ref>

It uses [[Software:Cover Flow|Cover Flow]] for browsing History and Bookmarks, and made use of a new option called speculative loading, which automatically loads documents, scripts, and style information that are required to view a web page ahead of time. Top sites can display up to 24 thumbnails  based on the user's most frequently visited pages on startup.<ref name="apple.com2" />

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, and a button for adding bookmark is added to the address bar by default. The reload/stop button is now superimposed on the right end of the address bar. The desktop version of Safari 4 features a design more similar to the one used on the iPhone compared to Safari 3.<ref name="apple.com2" />

Safari 4 contains many improved developer tools including the Web Inspector, CSS element viewing, JavaScript debugger and profiler, offline table and database management with [[SQL]] support, and resource graphs. It also added supports for CSS image retouching effects, CSS Canvas, and HTML5 content. Safari 4 ran a Javascript engine that was 9 times faster than Internet Explorer 8, and about four times faster than Mozilla Firefox 3.<ref name="apple.com2" />

=== Safari 5 ===
[[File:Refinery CMS Dashboard-2.png|thumb|Refinery CMS Dashboard-2 in Safari 5]]
Apple released Safari 5 on June 7, 2010, featuring the new Safari Reader for reading articles on the web without distraction (based on Arc90's Readability tool<ref name="Safari 5: Another Step Towards Better Reading On The Web">{{cite web |url=http://blog.arc90.com/2010/06/07/safari-5-another-step-towards-better-reading-on-the-web |title=Safari 5: Another Step Towards Better Reading On The Web |author=Rich Ziade |date=June 7, 2010 |access-date=June 8, 2010 |archive-url=https://web.archive.org/web/20100813074353/http://blog.arc90.com/2010/06/07/safari-5-another-step-towards-better-reading-on-the-web |archive-date=August 13, 2010}}</ref>), and a 30 percent JavaScript performance increase over Safari 4. Safari 5 includes improved developer tools and supports more than a dozen new HTML5 technologies focused on interoperability. Since Safari 5, developers can create secure Safari Extensions to customize and enhance the browsing experience.<ref>{{cite press release |url=https://www.apple.com/newsroom/2010/06/07Apple-Releases-Safari-5/ |title=Apple Releases Safari 5 |date=June 7, 2010 |publisher=Apple |access-date=December 1, 2018}}</ref> Apple also re-added the progress bar behind the address bar in this release. Safari 5.0.1 enabled the Extensions PrefPane by default; previously, users had to enable it via the Debug menu.

== Security ==

=== Plugins ===
Apple used a remotely updated plug-in blacklist to prevent potentially dangerous or vulnerable plugins from running on Safari. Initially, Flash and Java contents were blocked on some early versions of Safari. Since Safari 12 support for NPAPI plugins (except for Flash) has been completely dropped. Starting with the release of Safari 14, support for Adobe Flash Player will be dropped altogether.<ref name="flash"/>

=== Browser exploits ===

An overview and detailed information about Safari exploits are [https://www.cvedetails.com/product/2935/Apple-Safari.html listed by CVE Details].

In the [[Software:Pwn2Own|PWN2OWN]] contest at the 2008 CanSecWest security conference in Vancouver, British Columbia, Safari caused Mac OS X to be the first OS to fall in a hacking competition. Participants competed to find a way to read the contents of a file located on the user's desktop in one of three operating systems: Mac OS X Leopard, Windows Vista SP1, and [[Software:Ubuntu (operating system)|Ubuntu]] 7.10. On the second day of the contest, when users were allowed to physically interact with the computers (the prior day permitted only network attacks), Charlie Miller compromised Mac OS X through an unpatched vulnerability of the [[Software:Perl Compatible Regular Expressions|PCRE library]] used by Safari.<ref name="miller">{{cite news |first=Robert |last=McMillan |title=Mac hack contest bug had been public for a year |url=https://www.macworld.com/article/1133098/hack.html |work=Macworld |publisher=IDG |date=April 22, 2008 |access-date=May 1, 2018}}</ref> Miller was aware of the flaw before the conference and worked to exploit it unannounced, as is the common approach in these contests.<ref name="miller" /> The exploited vulnerability and other flaws were patched in Safari 3.1.1.<ref>{{cite web|url=http://www.computerworld.com/s/article/9078399/Update_Apple_patches_Safari_s_10_000_bug_fixes_other_flaws|title=Update: Apple patches Safari's $10,000 bug, fixes other flaws|author=Gregg Keizer|date=April 17, 2008|work=Computerworld|access-date=September 12, 2015}}</ref>

In the 2009 PWN2OWN contest, Charlie Miller performed another exploit of Safari to hack into a Mac. Miller again acknowledged that he knew about the security flaw before the competition and had done considerable research and preparation work on the exploit.<ref>{{cite web|last=Foresman|first=Chris|title=Pwn2Own winner says Macs are more safe, though less secure|url=https://arstechnica.com/apple/2009/03/pwn2own-winner-says-macs-are-more-safe-though-less-secure/|publisher=Ars Technica}}</ref><ref>{{cite web |url=http://news.softpedia.com/news/Charlie-Miller-Wins-Pwn2Own-Again-Thanks-to-Safari-Flaw-107269.shtml |title=Charlie Miller Wins Pwn2Own Again Thanks to Safari Flaw |date=March 19, 2009}}</ref> Apple released a patch for this exploit and others on May 12, 2009 with Safari 3.2.3.<ref>{{cite web |url=http://support.apple.com/kb/HT3550|title=About the security content of Safari 3.2.3|date=May 12, 2009|publisher=Apple Inc.|access-date=December 22, 2009}}</ref><ref>{{Cite web|date=May 12, 2009|title=Safari 3.2.3 improves security|url=https://www.macworld.com/article/1140569/safari323.html|access-date=October 11, 2020|website=Macworld|language=en}}</ref>

=== 64-bit builds ===
The version of Safari included in Mac OS X v10.6 (and later versions) is [[Compiler|compiled]] for 64-bit architecture. Apple claims that running Safari in 64-bit mode will increase rendering speeds by up to 50%.

On 64-bit devices, iOS and its stock apps are 64-bit builds including Safari.<ref>{{cite web|url=https://www.apple.com/apple-events/september-2013/|title=Apple Events - Special Event September 2013 - Apple|access-date=September 12, 2015}}</ref><ref>{{cite web|url=https://www.engadget.com/2013/09/10/ios-7-64-bit/|title=iOS 7 will be 64-bit, just like the iPhone 5s' new A7 chip|author=Dana Wollman|publisher=AOL|work=Engadget|access-date=September 12, 2015}}</ref>

== Criticism ==

=== Distribution through Apple Software Update ===
An earlier version of Apple Software Update (bundled with Safari, [[Software:QuickTime|QuickTime]], and iTunes for Microsoft Windows) selected Safari for installation from a list of Apple programs to download by default, even when it did not detect an existing installation of Safari on a user's machine. John Lilly, former CEO of Mozilla, stated that Apple's use of its updating software to promote its other products was "a bad practice and should stop." He argued that the practice "borders on malware distribution practices" and "undermines the trust that we're all trying to build with users."<ref name="Webware Lilly">{{cite web |first=Martin |last=LaMonica |title=Mozilla CEO says Apple's Safari auto-update 'wrong' |url=http://news.cnet.com/8301-17939_109-9901006-2.html |publisher=CNET Networks |date=March 21, 2008 |access-date=June 12, 2008}}</ref> Apple spokesman Bill Evans sidestepped Lilly's statement, saying that Apple was only "using Software Update to make it easy and convenient for both Mac and Windows users to get the latest Safari update from Apple."<ref>{{cite web|url=http://www.informationweek.com/news/internet/webdev/showArticle.jhtml?articleID=206905039|title=Apple Distributes Safari Via Software Update|work=InformationWeek|access-date=September 12, 2015}}</ref> Apple also released a new version of Apple Software Update that puts new software in its own section, though still selected for installation by default.<ref>{{cite news |first=Gregg |last=Keizer |title=Apple makes minor concession on pushing Safari to Windows users |url=https://www.computerworld.com/article/2536579/enterprise-applications/apple-makes-minor-concession-on-pushing-safari-to-windows-users.html |work=Computerworld |publisher=IDG |date=2008-04-17 |access-date=April 19, 2008}}</ref> By late 2008, Apple Software Update no longer selected new installation items in the new software section by default.<ref>{{cite web|date=2013-09-16|author=Verge Staff|url=https://www.theverge.com/2011/12/13/2612736/ios-history-iphone-ipad|title=iOS: A visual history|publisher=The verge|accessdate=2021-05-18}}

Users left exposed |author=Joshua Long |publisher=Sophos Ltd. |date=July 30, 2012 |access-date=July 30, 2012}}</ref> while there were over 121 vulnerabilities left unpatched on those platforms.<ref>{{cite web |url=http://support.apple.com/kb/HT5400 |title=About the security content of Safari 6 |publisher=Apple Inc. |date=July 25, 2012}}</ref> Since then, Snow Leopard has had only three minor version releases (the most recent in September 2013<ref>{{cite web | url=http://support.apple.com/kb/DL1569 | title=Safari 5.1.10 for Snow Leopard | publisher=support.apple.com | date=September 12, 2013 | access-date=February 5, 2015}}</ref>), and Windows has had none.<ref>{{cite web | url=http://support.apple.com/kb/DL1531 | title=Safari 5.1.7 for Windows | publisher=support.apple.com | date=May 9, 2012 | access-date=February 5, 2015}}</ref> While no official word has been released by Apple, the indication is that these are the final versions available for these operating systems, and both retain significant security issues.<ref>{{cite web | url=http://www.pcper.com/news/General-Tech/Apple-No-Longer-Updating-Safari-Windows-Users-Should-Switch-More-Secure-Browser | title=Apple No Longer Updating Safari for Windows, Users Should Switch To A More Secure Browser | publisher=pcper.com | date=August 6, 2012 | access-date=February 5, 2015}}</ref><ref>{{cite web | url=http://www.tuaw.com/2014/02/28/apple-isnt-updating-snow-leopard-anymore-heres-what-you-shoul/ | title=Apple isn't updating Snow Leopard anymore, here's what you should know | publisher=tuaw.com | date=February 28, 2014 | access-date=February 5, 2015}}</ref>

=== Failure to adopt modern standards ===
While Safari pioneered several now standard HTML5 features (such as the Canvas API) in its early years, it has come under attack<ref>{{cite web|date=2015-06-30|author=Nolan Lawson|url=https://nolanlawson.com/2015/06/30/safari-is-the-new-ie/|title=Safari is the new IE|publisher=Read the Tea Leaves|accessdate=2021-05-18}}</ref> for failing to keep pace with some modern web technologies. Since 2015, iOS has allowed third party web browsers to be installed, including Chrome, Firefox, Opera and Edge; however, they are all forced to use the underlying WebKit browser engine, and inherit its limitations.<ref>{{Cite web|last=May 2|first=April Berthene {{!}}|last2=2017|date=May 2, 2017|title=Apple keeps Safari at Chrome's core, and that's a drag on consumers' mobile experience|url=https://www.digitalcommerce360.com/2017/05/02/apples-dirty-little-secret-about-chrome/|access-date=March 22, 2021|website=Digital Commerce 360|language=en-US}}</ref><ref>{{cite web|url=https://fieldguide.gizmodo.com/how-to-pick-the-best-browser-for-your-phone-1819261780|title=How to Pick the Best Browser for your Phone|date=September 10, 2017|publisher=Gizmodo}}</ref>

=== Intentionally limiting ad blockers and tracking protection ===
Beginning in 2018, Apple made technical changes to Safari's content blocking functionality which prompted backlash from users<ref>{{Cite web|url=https://apple.slashdot.org/story/19/09/23/210220/apple-neutered-ad-blockers-in-safari-but-unlike-chrome-users-didnt-say-a-thing|title=Apple Neutered Ad Blockers In Safari, But Unlike Chrome, Users Didn't Say a Thing - Slashdot|website=apple.slashdot.org|language=en|access-date=September 24, 2019}}</ref> and developers<ref>{{Cite web|url=https://www.zdnet.com/article/apple-neutered-ad-blockers-in-safari-but-unlike-chrome-users-didnt-say-a-thing/|title=Apple neutered ad blockers in Safari, but unlike Chrome, users didn't say a thing|last=Cimpanu|first=Catalin|website=ZDNet|language=en|access-date=September 24, 2019}}</ref> of ad blocking extensions, who said the changes made it impossible to offer a similar level of user protection found in other browsers. Internally, the update limited the number of blocking rules<ref>{{Cite web|url=https://nakedsecurity.sophos.com/2019/09/24/apple-restricts-adblocking-extensions/|title=Apple restricts old adblocking tech|date=September 24, 2019|website=Naked Security|language=en|access-date=September 24, 2019}}</ref> which could be applied by third-party extensions, preventing the full implementation of community-developed blocklists. In response, several developers of popular ad and tracking blockers announced their products were being discontinued,<ref>{{Cite web|url=https://www.macobserver.com/link/safari-13-ublock-origin/|title=Safari 13 Just Killed uBlock Origin and Other Extensions|website=The Mac Observer|language=en-US|access-date=September 24, 2019}}</ref> as they were now incompatible with Safari's newly limited content blocking features. As a matter of policy, Apple requires the use of [[Software:WebKit|WebKit]],<ref>{{Cite web|url=https://www.howtogeek.com/184283/why-third-party-browsers-will-always-be-inferior-to-safari-on-iphone-and-ipad/|title=Why Third-Party Browsers Will Always Be Inferior to Safari on iPhone and iPad|last=Hoffman|first=Chris|website=How-To Geek|language=en-US|access-date=September 24, 2019}}</ref> Safari's underlying rendering engine, in all browsers developed for its iOS platform, preventing users from installing any competing product which offers full ad blocking functionality. Beginning with Safari 13, popular extensions such as [[Software:UBlock Origin|uBlock Origin]] will no longer work.<ref>{{Cite news|last=Cimpanu|first=Catalin|date=September 21, 2019|title=Apple neutered ad blockers in Safari, but unlike Chrome, users didn't say a thing|work=ZDNet|url=https://www.zdnet.com/article/apple-neutered-ad-blockers-in-safari-but-unlike-chrome-users-didnt-say-a-thing/|access-date=November 27, 2020}}</ref>
== Market share ==
In 2009, Safari had a market share of 3.85%.<ref name="SC1">{{cite web|date=2009|author=Gs.statcounter|url=https://gs.statcounter.com/browser-market-share/all/worldwide/2009|title=Browser Market Share Worldwide of 2009|publisher=Statcounter|accessdate=2021-05-19}}</ref> After remaining stable for nearly three years, it had finally caught up with Firefox by late 2014.<ref name="SC2">{{cite web|date=2014|author=Gs.statcounter|url=https://gs.statcounter.com/browser-market-share/all/worldwide/2014|title=Browser Market Share Worldwide of 2014|publisher=Statcounter|accessdate=2021-05-19}}</ref> A year later, Safari was ranked the second most used browser worldwide after Google Chrome, with a 13.01% [[Software:Usage share of web browsers|usage share]].<ref name="SC3">{{cite web|date=2015|author=Gs.statcounter|url=https://gs.statcounter.com/browser-market-share/all/worldwide/2015|title=Browser Market Share Worldwide of 2015|publisher=Statcounter|accessdate=2021-05-19}}</ref>

As of 2021, Google Chrome continued to be the most popular web browser, with Safari closely behind in second place.<ref name="SC4">{{cite web|date=2009|author=Gs.statcounter|url=https://gs.statcounter.com/browser-market-share|title=Browser Market Share Worldwide of 2021|publisher=Statcounter|accessdate=2021-05-19}}</ref><br>

== Safari Developer Program ==
The Safari Developer Program was a free program for writers of extensions and [[HTML5]] websites. It allowed members to develop extensions for [[Company:Apple Inc.|Apple's]] Safari [[Software:Web browser|web browser]]. Since WWDC 2015, it is part of the unified Apple Developer Program, which costs $99 a year.<ref>{{cite web|date=2015-06-10|author=Joe Rossignol|url=https://www.macrumors.com/2015/06/10/new-safari-extensions-gallery-fee/|title=OS X El Capitan to Bring New Safari Extensions Gallery as Part of Unified $99 Developer Program|publisher=Macrumors|accessdate=2021-05-18}}</ref>
