Opera Dragonfly
Opera Software's Opera Dragonfly is a new suite of open-source debugging tools for Web developers and designers that got its name because "it eats bugs". The suite covers the full debugging work flow, from inspecting network access and downloaded resources to correcting JavaScript issues and seeing how CSS rules apply to the DOM. Opera Dragonfly supports all the newest Web technologies, including SVG and HTML5 APIs, such as Web Storage. Product benefits, sayeth Opera, include a superior JavaScript debugger, a network inspector to discover why a site "turns to molasses" and a storage inspector to uncover how a site handles the data it collects. Opera Dragonfly loads automatically when one downloads the Opera browser.
