The opera web browser is the flagship product of Opera Software. It is a web browser that competes directly for market share with Mozilla Firefox, Microsoft Internet Explorer and other popular web browsers. It has historically had a minuscule share of the browser market, in part due to its price and partly because it has no way of persuading users; which are satisfied with whatever comes on their computer out of the box. Opera has a very robust version of its web browser for PDAs, cell phones, and other hand held devices called Opera mini.
