opera web browser 12.13

Windows/Mac/Linux: Opera is a rock-solid browser with roots stretching back to 1994. Many of the features baked right into Opera are either not implemented in other browsers, or require multiple extensions at the cost of system resources—navigation by mouse gestures is one of the flashier examples. Despite being feature-packed, Opera has a fairly small market share, due largely in part to being trialware up until 2000 and advertisement-supported until 2005—many people were turned off by the expense, if not the ads. Still, Opera proponents have long claimed that Opera beats Internet Explorer and Firefox when it comes to speedy rendering. Another selling point for Opera is the quality of the built-in tools. For many users, the built-in RSS reader, email client, and BitTorrent client do their jobs admirably, cutting down on the number applications they need running at once. Opera is extensible, but the pool of available extensions is radically smaller than that available for Firefox.

Opera is a web browser and Internet suite developed by Opera Software with over 270 million users worldwide.^[6] The browser handles common Internet-related tasks such as displaying web sites, sending and receiving e-mail messages, managing contacts, chatting on IRC, downloading files via BitTorrent, and reading web feeds.
