Opera is a web browser and Internet suite developed by Opera Software with over 300 million users worldwide.[5][non-primary source needed] The browser handles common Internet-related tasks such as displaying web sites, sending and receiving e-mail messages, managing contacts, chatting on IRC, downloading files via BitTorrent, and reading web feeds. Opera is offered free of charge for personal computers and mobile phones.
Opera Mini, which is the third most popular[6] mobile web browser as of March 2013, has been chosen as the default integrated web browser in several mobile handsets[7][8][9] by their respective manufacturers.
Features include tabbed browsing, page zooming, mouse gestures, and an integrated download manager. Its security features include built-in phishing and malware protection and the ability to delete private data such as HTTP cookies. Opera has been noted for originating many features later adopted by other web browsers.[10][11]
Opera runs on a variety of personal computer operating systems, including Microsoft Windows, Mac OS X, Linux, and FreeBSD. Opera editions are available for devices using the Maemo, Bada, BlackBerry, Symbian, Windows Mobile, Android, and iOS operating systems, and Java ME.[12][13][14] Approximately 120 million mobile phones have been shipped with Opera.[15] Opera is the only commercial web browser available for the Nintendo DS and Wii gaming systems. Some television set-top boxes as well as TV-set use Opera to render HTML-based interactive content. Adobe Systems has licensed Opera technology for use in the Adobe Creative Suite.[16][17]
Up to version 12.02, released on August 30, 2012, Opera was the only one of the major web browsers that still actively supported Windows 2000 in new releases.
