what is Opera?

[Engineer]

Opera is a very popular alternative Web browser. It offers features like tabbed browsing and pop-up blocking (in fact, Opera was one of the first browsers to offer tabbed browsing). Plus it includes other useful features like zoom and "fit to window width" to make all the pages you view easier for you to read.

Opera
Opera provides all the features you've come to expect from top-of-the-line Web browsers. But it also comes with things like Zoom and "fit in window". And best of all, Opera is now available for free.

Opera Mobile
Now you can get Opera for your mobile phone and view many of the same pages you view on your computer right from your phone.
