Requires: Nightly build of WebKit/Safari
Drosera is a JavaScript debugger for WebKit/Safari that can be used with any application that uses WebKit. Like the Web Inspector, over 90% of it is written in HTML, CSS and JavaScript.
Drosera is included with all of the WebKit nightly builds, or you can build it yourself by running the build-drosera tool found in WebKitTools/Scripts.
