The history of the 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 ASA, with the first publicly available version released in 1996.Opera has undergone extensive changes and improvements, and introduced notable features such as Speed Dial.
The Opera browser was, until version 2.0, called MultiTorg Opera and was not available to the public--although online documents show it at The Third International WWW Conference in 1995. 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 W3C standards.
In February 2013, Opera Software announced that their in-house rendering engine, Presto, would be phased out in favour of WebKit. Opera 15 saw the browser being fully rewritten, with this and subsequent releases being based on Blink and Chromium.

Version 2.0, the first public release of Opera, was released as shareware in 1996.
Due to popular demand, Opera Software showed interest in programming its browser for alternate operating systems such as Apple Macintosh, QNX and BeOS. On October 10, 1997, they launched "Project Magic", an effort to determine who would be willing to purchase a copy of their browser in their native OS, and to properly distribute funds to develop or outsource for such operating systems. On November 30, 1997 they closed voting for which operating system to develop with. Project Magic then became a news column for updates for alternate operating systems until version 4.
In 1998, Opera 3.5 was released, adding Cascading Style Sheets (CSS) support and file upload capability.
Version 3.6 was released on May 12, 1999.
On June 28, 2000, Opera 4 for Windows (Elektra) was released, introducing a new cross-platform core, and a new integrated e-mail client.
Opera 5, released on December 6, 2000, was the first version which was ad-sponsored instead of having a trial period. Version 5 also supported ICQ, but this was dropped from later versions.
Opera supported OS/2 for the first time, requiring WarpIN and Odin to be installed.
Opera 5.10 (April 2001) was the first version to recognize mouse gestures, but this feature was disabled by default.
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.
First MSN.com controversy:
On October 24, 2001, Microsoft blocked users of browsers other than Internet Explorer, including Opera, from accessing MSN.com. Microsoft Internet Explorer users were not affected. After cries of monopolistic behavior, Microsoft lifted the restrictions after two days. However, as late as November 2001, Opera users were still locked out from some MSN.com content, despite Opera's ability to display the content if MSN.com were to serve it.
On January 28, 2003, Opera 7 was released, introducing the new "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. The new engine brought almost full support for the HTML 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 and Safari were offered free of charge without including advertisements.
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, 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 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 used for old versions of Microsoft Internet Explorer. Other browsers received either a style sheet tailored to them, or at least the latest Internet Explorer style sheet. The outdated style sheet that Opera received caused Opera to move a significant amount of MSN.com's content 30 pixels to the left of where it should be, distorting the page and making it appear as though there was a bug in Opera.
In response, the Opera Software company created a special "Bork" edition of Opera which displayed gibberish instead of MSN.com but not on any other web site. They did this to make a point about the necessity of a harmonious relationship between web browsers and web sites.
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.

Version 8.5 was released on September 20, 2005, Opera announced that their browser would be available free of charge and without advertisements from then onwards, although the company still sells support contracts. Enhancements included: automatic client-side fixing of web sites that did not render correctly, and a number of security fixes.

Version 9.1 (released in 2006) introduced fraud protection using technology from GeoTrust, a digital certificate provider, and PhishTank, an organization that tracks known phishing web sites.
Version 9.2, codenamed Merlin, introduced Speed Dial, 3 × 3 small thumbnails which are shown instead of a blank page.
Version 9.5, codenamed Kestrel (after the Kestrel falcon), was released to span the gap between Opera 9.2 and Opera 10. It included some of the rendering improvements due to be made in Opera 10 and also aimed to provide better integration with various operating systems. The first alpha build of Opera 9.5 was released on September 4, 2007. The first public beta was released on October 25, 2007, and the final version was released on June 12, 2008.

Opera 9.5 has improved support for Cascading Style Sheets (CSS), including many more CSS3 selectors and the CSS2 text-shadow property. Support for other web standards was also improved. For example, Opera 9.5's Scalable Vector Graphics (SVG) implementation supports 93.8% of the W3C's SVG test suite, and built-in support for Animated Portable Network Graphics (APNG) and MathML. Opera 9.5 also supports high-security Extended Validation Certificates and added malware protection through partnership with Haute Secure.

Opera 9.5 also lets users save bookmarks, notes, the Personal Bar and Speed Dial settings to the Opera Link service.
