JDownloader is open source, platform independent, and written completely in Java. It simplifies downloading files from One-Click-Hosters like Rapidshare.com or Megaupload.com - not only for users with a premium account but also for users who don't pay.

Google Chrome is a web browser developed by Google that uses the WebKit layout engine. It was first released as a beta version for Microsoft Windows on September 2, 2008, and the public stable release was on December 11, 2008. In September 2008, Google released a large portion of Chrome's source code, including its V8 JavaScript engine, as an open source project entitled Chromium. This move enabled third-party developers to study the underlying source code and to help port the browser to the Mac OS X and Linux operating systems.Chromium implements a similar feature set as Chrome, but lacks built-in automatic updates, built-in PDF reader and Google branding, and most noticeably has a blue-colored logo in place of the multicolored Google logo.
