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
and page zoom, a variety of mouse pointer skins, and an integrated
load 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.
