The '''history of the [[Opera (web browser)|Opera]] web browser''' began in 1994 when it was started as a research project at [[Telenor]], the largest Norwegian telecommunications company. In 1995, the project branched out into a separate company named [[Opera Software]] [[Allmennaksjeselskap|ASA]],<ref>{{cite web

}}</ref> Opera has undergone extensive changes and improvements, and introduced notable features such as Speed Dial.

Until version 2.0, the Opera browser was called MultiTorg Opera (version 1.0) and had only a limited internal release—although it was demonstrated publicly at the [[International World Wide Web Conference|Third International WWW Conference]] in April 1995.<ref>{{cite web|url=http://www.igd.fhg.de/archive/1995_www95/proceedings/posters/31/|title=MultiTorg Opera|access-date=11 June 2014|publisher=www.igd.fhg.de|archive-url=https://web.archive.org/web/20020824150540/http://www.igd.fhg.de/archive/1995_www95/proceedings/posters/31/|archive-date=August 24, 2002 }}</ref><ref>{{cite web|title=Opera 1.0 series|url=http://www.opera.com/docs/history/presto/|publisher=Opera Software|access-date=26 November 2013|date=5 February 2013}}</ref> It was known for its [[multiple document interface]] (MDI) and 'hotlist' (sidebar), which made browsing several pages at once much easier, as well as being the first browser to completely focus on adhering to the [[World Wide Web Consortium|W3C]] standards.{{citation needed|date=June 2017}}

In February 2013, Opera Software announced that their in-house rendering engine, [[Presto (layout engine)|Presto]], would be phased out in favour of [[WebKit]].<ref>{{cite web

Due to popular demand, Opera Software showed interest in programming its browser for alternative operating systems such as [[Macintosh|Apple Macintosh]], [[QNX]] and [[BeOS]]. On October 10, 1997, they launched "Project Magic", an effort to measure user interest in the development of new Opera releases for other operating systems, in order to fund the development of a new version appropriately.<ref>{{cite web|url=http://www.operasoftware.com/alt_os1.html |title=Opera Software - Opera for OS/2, Mac, X11, BeOS... |author=Helmar Rudolph |archive-date=February 12, 1998 |work=operasoftware.com |url-status=dead |archive-url=https://web.archive.org/web/19980212101338/http://www.operasoftware.com/alt_os1.html }}</ref> On November 30, 1997 they closed voting for which operating system to develop with.

==Elektra versions==
===Version 3.5/3.6===

In 1998, Opera 3.5 was released, adding [[Cascading Style Sheets]] (CSS) support,<ref name="Rijk"/> [[TLS 1.0]]<ref>{{cite web|url=https://help.opera.com/en/operas-archived-history/|title=Opera's archived version history 1-12|access-date=2024-06-03}}</ref> the Elektra rendering engine, and file upload capability.<ref>{{cite web|url=http://www.blooberry.com/indexdot/history/opera.htm|title=Browser History: Opera|last=Wilson|first=Brian|access-date=2008-02-19}}</ref>

Since version 3.5, Opera has supported CSS, and [[Håkon Wium Lie]], one of the inventors of CSS, is the [[Chief technology officer|CTO]] at Opera.<ref>[http://www.meyerweb.com/eric/articles/webrev/199906.html CSS: If not now, when?], Eric Meyer, June 1999, retrieved on October 25, 2005</ref> Up to 6.0 Opera supported most common web standards, Netscape plugins and some other recent standards such as [[Wireless Application Protocol|WAP]] and [[Wireless Markup Language|WML]] for wireless devices, but its implementation of advanced [[ECMAScript]] (of which "JavaScript" is an implementation) and the [[HTML]] [[Document Object Model]] was poor.

Version 3.6 was released on May 12, 1999.<ref>{{cite press release|url=http://www.opera.com/press/releases/1998/12/15/|title=Opera Software Releases 3.60|publisher=[[Opera Software]]|date=December 15, 1998|access-date=2008-12-10}}</ref> The 16-bit version of Opera for Windows 3.62 is the last version to support [[Windows 3.x]].

===Version 5===
[[File:Opera 5.02.png|thumb|Opera 5.02 on Windows XP]]

Opera 5, released on December 6, 2000, was the first version which was [[Adware|ad-sponsored]] instead of having a trial period.<ref>{{cite press release

Opera supported [[OS/2]] for the first time, requiring [[WarpIN]] and [[Odin (code conversion software)|Odin]] to be installed.<ref>{{cite web|last=Watson|first=Dave|title=A Quick Look at Opera|url=http://www.scoug.com/os24u/2001/opera.html|publisher=The Southern California OS/2 User Group|access-date=August 16, 2010|date=July 21, 2001}}</ref>

Opera 5.10 (April 2001) was the first version to recognize mouse gestures, but this feature was disabled by default.

===Version 6===
[[File:Opera 6.0.png|thumb|Opera 6.0]]
On November 29, 2001, Opera 6 was released with new features including [[Unicode]] support, and offering a [[single document interface]] as well as the [[multiple document interface]] allowed by previous versions.<ref>{{cite press release|url=https://press.opera.com/2001/11/29/simply-the-best-internet-experience-3/ |title=Opera 6.0 for Windows launched after record-breaking beta |publisher=[[Opera Software]] |date=November 29, 2001 |access-date=August 19, 2019}}</ref>

====First MSN.com controversy====
On October 24, 2001, [[Microsoft]] blocked users of browsers other than Internet Explorer, including Opera, from accessing [[MSN]].com. After accusations of monopolistic behavior, Microsoft lifted the restrictions two days later.<ref>{{cite news

== Presto versions ==
{{Cleanup rewrite|it reads like a time line after Version 8|date=June 2022|section=yes}}

===Version 7===
[[File:Opera 7.02.png|thumb|Opera 7.02]]
On January 28, 2003,<ref>{{cite press release
|url=http://www.opera.com/pressreleases/en/2003/01/28/
|title=Opera 7 Ready to Rock the Web
|publisher=[[Opera Software]]

|access-date=2008-02-19
}}</ref> Opera 7 was released, introducing the new "[[Presto (layout engine)|Presto]]" layout engine, with improved CSS, [[client-side scripting]], and [[Document Object Model]] (DOM) support. [[Mac OS 9]] support was dropped.

Version 7.0 saw Opera undergo an extensive rewrite with the faster and more powerful [[Presto (layout engine)|Presto layout engine]]. The new engine brought almost full support for the HTML [[Document Object Model|DOM]] meaning that parts of, or a whole, page can be re-rendered in response to DOM and script events.

A 2004 review in ''[[The Washington Post]]'' described Opera 7.5 as being excessively complex and difficult to use. The review also criticized the free edition's use of obtrusive advertisements when other browsers such as [[Mozilla Application Suite|Mozilla]] and [[Safari (web browser)|Safari]] were offered free of charge without including advertisements.<ref>{{cite news

In August 2004, Opera 7.6 began limited alpha testing. It had more advanced standards support, and introduced voice support for Opera, as well as support for Voice XML. Opera also announced a new browser for Interactive Television, which included a ''fit to width'' option Opera 8 introduced. Fit to Width is a technology that initially utilized the power of CSS, but it is now internal Opera technology. Pages are dynamically resized by making images and/or text smaller, and even removing images with specific dimensions to make it fit on any screen width, improving the experience on smaller screens dramatically. Opera 7.6 was never officially released as a final version.

On January 12, 2005, Opera Software announced that it would offer free licenses to higher education institutions,<ref>[http://www.opera.com/pressreleases/en/2005/01/12/ Students surf safely with Opera: Opera site license free for educational institutions], January 12, 2005, retrieved on October 25, 2005</ref> a change from the previous cost of $1,000 USD for unlimited licenses. Schools that opted for the free license included [[Massachusetts Institute of Technology]] (MIT), [[Harvard University]], [[University of Oxford]], [[Georgia Institute of Technology]], and [[Duke University]]. Opera was commonly criticized for having been [[Adware|ad-sponsored]], since this was seen as a barrier to gaining market share. In the newer versions the user was allowed a choice of generic graphical banners, or text-based targeted advertisements provided by Google based upon the page being viewed. Users could pay a license fee to remove the advertisement bar.

====Second MSN.com controversy====
In 2003, MSN.com was configured to present Opera browsers with a [[Style sheet (web development)|style sheet]] used for old versions of Microsoft [[Internet Explorer]].<ref>{{cite news

}}</ref> The outdated style sheet that Opera received caused Opera to move a significant amount of MSN.com's content 30 [[pixel]]s to the left of where it should be, distorting the page and making it appear as though there was a bug in Opera.<ref>{{cite news

In response, the [[Opera Software]] company created a special "[[:wikt:bork|Bork]]" edition of Opera which displayed gibberish instead of MSN.com but not on any other web site. They said they did this to make a point about the necessity of a harmonious relationship between web browsers and web sites.<ref name="Bork">{{cite press release

After the complaints, Microsoft changed their servers to present the latest version of Opera, version 7, with the style sheet served to the latest version of Internet Explorer, which resolved the problem. However, Microsoft continued to serve the outdated style sheet to the older Opera 6.<ref name="Why doesn't MSN work with Opera?"/><ref name="Bork"/>

====Hotmail controversy====
In November 2004, [[Opera Software]] sent an electronic message to [[Microsoft]], complaining that Opera users were sent an incomplete [[JavaScript]] file when using [[Outlook.com|Hotmail]] (now Outlook.com). The incomplete file prevented Opera users from emptying their "Junk E-mail" folders. The Opera Software company later sent a physical letter to Microsoft. Nevertheless, as of February 11, 2005, Microsoft had neither replied to the messages nor corrected the issue.<ref>{{cite web

Opera introduced [[Web widget|Widgets]], small web applications, a built-in [[BitTorrent (protocol)|BitTorrent client]], improved content blocking and a built-in tool for creating and editing search engines.
Opera also added ability to read [[MHTML]] and to save the web page as archives.

Version 9.6 improved Opera Link with the new opportunity to sync custom search engines and typed history. [[Web feed|Feed]] preview and an updated Opera Mail client were additional changes.

===Version 10===
Version 10 (Peregrine) debuted in a first beta version on June 3, 2009 and scored 100/100 on the [[Acid3]] test, but failed the smoothness criteria. There was also a preview build that scored 100/100, released on March 28, 2009. Among other features, it also came with speed optimizations, inline spell checking for forms, an auto update feature, HTML mail formatting, web fonts and SVG font support, alpha transparency support using the RGBA and HSLA color models, and an updated version of the Opera Dragonfly web debugger. Opera Turbo, a mode which uses Opera's servers as proxy servers with data compression, reducing volume of data transferred by up to 80% (depending upon content), and thus increasing speed, was introduced.

Opera 10 was officially released on September 1, 2009. Within a week of release, 10 million downloads had been recorded.

The 10.5x versions (codenamed Evenes) also came with a new [[JavaScript]] engine, Carakan, and a new graphics backend dubbed Vega (replacing the previously used Qt), that have increased its speed measurably. Then [[Opera 10#Opera 10`|version 10.60]], which Opera Software claims to be 50% faster than Opera 10.50, which also brought up new features like [[Geolocation]], [[WebM]] support, [[AVG Technologies|AVG]] [[malware]] protection, Speed Dial improvements, etc.

Opera 10.63 is the last version to support [[Windows 9x]] and [[Windows NT 4.0]], as later releases would require at least [[Windows 2000]].

===Version 11===
Opera 11 (codenamed Kjevik) was released on December 16, 2010 with new features including [[Software extension|extensions]], tab stacking, visual mouse gestures, new installer (Windows only) and safety improvements to the address field. In addition, the content blocker list now can be synchronized through Opera Link.<ref>{{cite web|url=http://www.opera.com/press/releases/2010/12/16/|title=Are you ready for Opera 11?|work=Opera Desktop Team|date=December 16, 2010|publisher=Opera Software|access-date=December 16, 2010}}</ref> It also passes the Acid3 Test as of January 22, 2011.

On April 12, 2011, Opera 11.10 (codenamed Barracuda) was released. It contains many fixes "under the hood", such as improved Turbo Mode, a plug-in installation wizard and a rewritten Speed Dial. Opera 11.10 was updated to use the new Presto 2.8 Rendering Engine.

===Opera 2013===

On February 12, 2013, Opera Software announced their intention to transition from their [[Presto (layout engine)|Presto]] layout engine to [[WebKit]], building upon the base of the [[Chromium (web browser)|Chromium project]]. Opera will become a contributor to the Chromium project.<ref>{{cite web|url=http://my.opera.com/ODIN/blog/300-million-users-and-move-to-webkit|title=Opera Press release |publisher=[[Opera Software]]|date=13 February 2013|archive-url=https://web.archive.org/web/20130214043259/http://my.opera.com/ODIN/blog/300-million-users-and-move-to-webkit|archive-date=February 14, 2013 }}</ref> After Google announced its transition of the Chrome/Chromium browser from WebKit to [[Blink (layout engine)|Blink]], Opera confirmed it would also switch to Blink instead of WebKit.<ref>{{cite web|last=Protalinski|first=Emil|title=Opera confirms it will follow Google and ditch WebKit for Blink, as part of its commitment to Chromium|url=https://thenextweb.com/insider/2013/04/04/opera-confirms-it-will-follow-google-and-ditch-webkit-for-blink-as-part-of-its-commitment-to-chromium/|publisher=The Next Web|access-date=29 May 2013|date=4 April 2013}}</ref>

The version identifier 13 was skipped, thought to be related to [[triskaidekaphobia|superstition]], while 14 was used to refer to a [[WebKit]]-based release of Opera for Android.

On July 2, 2013, the final version of Opera 15.0 was released. This release was not pushed through the automatic update system, as it was deemed some features important to current users had yet to be implemented.<ref>{{cite web|url=http://my.opera.com/desktopteam/blog/2013/07/02/opera-15|title=Opera 15 |publisher=[[Opera Software]]|date=2 July 2013|archive-url=https://web.archive.org/web/20130705214910/http://my.opera.com/desktopteam/blog/2013/07/02/opera-15|archive-date=July 5, 2013 }}</ref>
