Opera Dragonfly hunts for web bugs
Dragonfly, on the other hand, runs natively on PCs. Initial tests indicate that Dragonfly appears to work much more smoothly than Opera's previous tools. One article on Opera's developers' pages explains the program architecture, another explains how to use the tool. Opera intends to publish Dragonfly under the BSD license. A beta version of Opera 9.5 with integrated alpha version of Dragonfly is available for download from the Opera web site.
