OPERA

 The bottom line: Extensions, competitive page-load times, solid features, and good support for "future Web" technologies make Opera 12 an excellent browser, but it's treading water where it used to lead.

Review:
The second-oldest browser currently in use, Opera debuted way back in 1994 and continues to attract attention. Its feature-phone version claims more than 160 million users worldwide. While desktop Opera isn't quite as heavily used, it has developed a reputation as a leader on feature development, and can hold its own against the big four.

Opera covers the basics with tabbed browsing, mouse-over previews, a customizable search bar, advanced bookmarking tools, and simple integration with e-mail and chat clients. Mouse-gesture support, keyboard shortcuts, and drag-and-drop functionality round out the essentials.
