What is the Opera Web Browser?
Opera offers a clean, modern web browser that is an alternative to the other major providers. If you are unhappy with your current browser, consider Opera as a viable option. Opera provides their browsing software free of charge and is available on just about any device.
The original Opera web browser was released in 1995, as the result of a research project of a Norwegian telecommunications company. Since that time, the browser has received multitudes of updates in response to new innovations, and to keep pace with new technological innovations. Opera has a fast development cycle and experiments with new features and updates every two weeks.
