{{Main|History of the Opera web browser}}

In 1994, Jon Stephenson von Tetzchner and Geir Ivarsøy started developing the Opera web browser while working at Telenor, a Norwegian telecommunications company.{{Cite web|date=2020-02-14|title=From Norwegian research project to global multiplatform browser.

In 1995, they founded Opera Software AS.{{cite web|url=http://www.opera.com/company/ |archive-url=https://web.archive.org/web/20071203140601/http://www.opera.com/company/about/ |title=About Opera|publisher=Opera Software|archive-date=3 December 2007|access-date=5 September 2010}} Opera was initially released on 10 April 1995, and then it was released publicly in 1996 with version 2.10,{{cite web|url=http://www.foxkeh.com/downloads/history/history-original.pdf|title=Affiliated Organization of Firefox and Mozilla|publisher=Mozilla Foundation|website=Mozilla Japan|year=2006|access-date=5 September 2010}} which ran on Microsoft Windows 95.{{cite web|url=http://www.opera.com/company/history/|archive-url=https://web.archive.org/web/20071123104427/http://www.opera.com/company/about/milestones/|title=Milestones|publisher=Opera Software|archive-date=23 November 2007|access-date=13 January 2011|year=2007}} Development for mobile device platforms started in 1998.{{Cite web|date=2008-11-12|title=Can Opera Become to Mobile What Firefox has Become to the Computer?|url=https://www.fastcompany.com/1079768/can-opera-become-mobile-what-firefox-has-become-computer|access-date=2020-10-21|website=Fast Company|language=en-US}}

Opera 4.0, released in 2000, included a new cross-platform core that facilitated the creation of editions of Opera for multiple operating systems and platforms.{{cite web|url=http://www.markschenk.com/various/ohistory/index.html|title=Opera browser version history|last=Schenk|first=Mark|year=2010|access-date=11 June 2014}}

To this point, Opera was trialware and had to be purchased after the trial period. With version 5.0, released in 2000, Opera became ad-sponsored, displaying ads to users who had not paid for it.{{cite news|url=https://www.theregister.co.uk/2000/12/06/opera_browser_goes_free/|title=Opera browser goes free with version 5.0 launch|last=Lettice|first=John|website=The Register|date=6 December 2000|access-date=11 June 2014}} Subsequent versions have given users the choice of seeing banner ads or targeted text ads from Google.

With version 8.5, released in 2005, the ads were completely removed, and the browser's primary financial support came through revenue from Google (by contract, Opera's default search engine).{{cite news|url=http://www.searchenginejournal.com/opera-goes-free-with-help-from-google/2227/|title=Opera Goes Free with Help from Google|last=Baker|first=Loren|website=Search Engine Journal|date=20 September 2005|access-date=11 June 2014}}

Among new features introduced in version 9.1, released in 2006, was fraud protection using technology from GeoTrust, a digital certificate provider, and PhishTank, an organization that tracks known phishing web sites.{{cite web|url=http://operawatch.com/news/2006/12/opera-91-is-out-with-fraud-protection.html|title=Opera 9.1 is out with Fraud Protection|last=Goldman|first=Daniel|website=Opera Watch|date=18 December 2006|access-date=11 June 2014|archive-url=https://web.archive.org/web/20070105213820/http://operawatch.com/news/2006/12/opera-91-is-out-with-fraud-protection.html|archive-date=5 January 2007}} This feature was further expanded in version 9.5, when GeoTrust was replaced with Netcraft, and malware protection from Haute Secure was added.{{cite web|url=http://my.opera.com/desktopteam/blog/2008/06/06/malware-protection|title=Malware protection|last=Kleinhout|first=Huib|publisher=Opera Software|website=Opera Desktop Team|date=6 June 2008|access-date=11 June 2014|archive-url=https://web.archive.org/web/20080608110305/http://my.opera.com/desktopteam/blog/2008/06/06/malware-protection|archive-date=8 June 2008}}

In 2016, Opera was acquired by an investment group led by a Chinese consortium, the consortium included several Chinese companies such as Kunlun Tech and Qihoo 360. On July 27, 2018, Opera Software went public on the NASDAQ stock exchange, raising $115 million in its initial public offering.{{cite news|url=https://www.cnet.com/news/opera-browser-raises-115-million-in-initial-public-offering/|title=Opera browser raises $115 million in initial public offering|last=Shankland|first=Stephen|date=July 27, 2018|work=CNET|access-date=July 27, 2018}} Opera began repurchasing its shares in 2022 following the closure of 360 Security Technology Inc. that year.{{cite web |date=20 January 2022 |title=Opera Announces $50 Million Share Repurchase Program |url=https://www.prnewswire.com/news-releases/opera-announces-50-million-share-repurchase-program-301464928.html |access-date=21 March 2024 |website=PR Newswire |publisher=Opera Limited |language=English |quote=The Company plans to fund repurchases from its existing cash balance.

In January 2017, the source code of Opera 12.15, one of the last few versions still based on the Presto layout engine, was leaked.{{citation needed|date=March 2025}}

To demonstrate how radically different a browser could look, Opera Neon, dubbed a "concept browser", was released in January 2017. PC World compared it to demo models that automakers and hardware vendors release to show their visions of the future. Instead of a Speed Dial Browsing feature it displays the frequently accessed websites in resemblance to a desktop with computer icons scattered over it in an artistic formation.{{Cite web |url=https://www.pcworld.com/article/3156970/browsers/meet-opera-neon-operas-radical-vision-for-the-future-of-web-browsers.html |title=Meet Opera Neon, Opera's radical vision for the future of web browsers |work=PCWorld |date=11 January 2017 |first=Mark |last=Hachman}}{{Cite web|url=https://www.pcmag.com/review/350974/opera-neon|title=Opera Neon |website=PC Magazine |date=11 January 2017 |first=Michael |last=Muchmore}}

On 10 May 2017, Opera 45 was released. Notably this was the last version of the browser compatible with 32-bit Linux distributions, with later versions requiring a 64-bit Linux distribution. This version, inspired by the previous Opera Neon design, was called "Opera Reborn" and which redoes parts of the user interface, such as adding light and dark modes, and integrates the messenger applications Facebook Messenger, WhatsApp, and Telegram. Additionally, new ad-blocking settings were added along with security changes.{{Cite web |last=Kolondra |first=Krystian |date=2017-05-10 |title=Opera is Reborn |url=https://blogs.opera.com/desktop/2017/05/opera-is-reborn/ |access-date=2024-03-29 |website=Opera Desktop}}

On 4 January 2018, Opera 50 was released. This version updated the browser to utilize the built-in ad blocker to provide cryptocurrency mining protection that stops sites from running scripts that attempt to use the CPU to mine cryptocurrency. Additionally the browser added Chromecast support, VR support enhancements, saving pages as PDFs, and improved VPN performance with region-based locations rather than country-based.{{Cite web |last=Kolondra |first=Krystian |date=2018-01-04 |title=New year, new browser.

On 9 April 2019, Opera 60 was released.

The "Pinboards" feature was also added, letting users create a shareable collection of websites, images, links, and notes in a visual form. A video popout feature was also added for video conferencing, which happens automatically when switching tabs, popping out of the window when navigating away and popping back in when navigating back.{{Cite web |last=Kocemba |first=Maciej |date=2021-06-24 |title=Opera ships major new version of its desktop browser, codenamed R5 |url=https://blogs.opera.com/desktop/2021/06/opera-r5-desktop/ |access-date=2024-03-29 |website=Opera Desktop}} Later, in Opera 83 released on 19 January 2022, this feature would be implemented for all video players, not just video conferencing platforms.{{Cite web |last=Mielczarczyk |first=Kornelia |date=2022-01-19 |title=Opera 83 |url=https://blogs.opera.com/desktop/2022/01/opera-83/ |access-date=2024-03-29 |website=Opera Desktop}}

Opera Software uses a release cycle consisting of three "streams", corresponding to phases of development, that can be downloaded and installed independently of each other: "developer", "beta", and "stable". New features are first introduced in the developer build, then, depending on user feedback, may progress to the beta version and eventually be released.{{cite web|title=What is Opera, Opera next, and Opera developer?|url=http://blogs.opera.com/desktop/streams/|website=Opera Desktop Team Blog|date=14 January 2014 |access-date=16 September 2014}}

The developer stream allows early testing of new features, mainly targeting developers, extension creators, and early adopters. Opera developer is not intended for everyday browsing as it is unstable and is prone to failure or crashing, but it enables advanced users to try out new features that are still under development, without affecting their normal installation of the browser. New versions of the browser are released frequently, usually a few times a week.{{cite web|title=Opera Developer official page|url=http://www.opera.com/developer|access-date=20 November 2013|publisher=Opera Software|archive-url=https://web.archive.org/web/20160617183330/http://www.opera.com/developer|archive-date=17 June 2016|url-status=dead}}

The beta stream, formerly known as "Opera Next", is a feature complete package, allowing stability and quality to mature before the final release. A new version is released every couple of weeks.{{cite web|title=Opera beta|url=http://www.opera.com/beta|publisher=Opera Software ASA|access-date=9 November 2014|archive-url=https://web.archive.org/web/20191019020724/https://www.opera.com/computer/beta|archive-date=19 October 2019|url-status=dead}} Both streams can be installed alongside the official release without interference. Each has a different icon to help the user distinguish between the variants.{{cite web|title=Opera stream icons|url=https://www-static-blogs.operacdn.com/multi/wp-content/uploads/sites/2/2015/10/new-icons-1024x535.jpg|url-status=dead|access-date=2 May 2022|archive-date=7 December 2016|archive-url=https://web.archive.org/web/20161207194948/http://www-static-blogs.operacdn.com/multi/wp-content/uploads/sites/2/2015/10/new-icons-1024x535.jpg}}
