Opera Software has launched version 10.50 of its web browser – which it claims is the world’s “fastest” for Windows-based systems.

The latest iteration of the browser also includes a redesigned GUI, along with a feature known as “private browsing” which attempts to hide all traces of visited sites.

“Opera 10.50 is the fastest browser in almost all speed tests. But, more important than any speed test is the real-world speed during use. We designed Opera 10.50 to be easy to use, while making our unique features stand out, so you can get more out of the Web,” explained Opera CEO Lars Boilesen.

“Under the hood, we introduced a new JavaScript engine, Carakan and a new graphics library, Vega. What that means to you: no more waiting around for a site to load. [And] on Windows 7/Vista, we let Opera enjoy Aero Glass, as well as supporting Aero Peek and Jump Lists.”

Other features include:

  • Opera Turbo – Compresses Web pages on Opera’s servers and facilitates the faster transfer of data.
  • Unite – Allows users to share content immediately without uploading files or posting to a social network.
  • Link – Synchronizes speed dial, notes, search-engine preferences and more. Can be used across multiple Opera browsers.
