The Opera browser is used for general Internet applications such as
browsing the web, receiving and sending email messages, managing
communications, RCC online chat, downloading bit torrents, and
reading web feeds. Opera is available for free for computers,
mobile phones, and tablets. Opera was launched as a research
project at Telenor, Norway's largest telecommunications company.
The main components of Opera are tab-based browsing, small
features, page zoom, a variety of mouse pointer skins, and an
integrated upload management section. In terms of security, Opera
has built-in protection against phishing attacks and software
called malware, as well as the ability to stay safe when browsing
websites and delete personal information like cookies.
