That said, Dragonfly is very good. It offers a familiar set of features such as:
- DOM inspection, editing and change monitoring
- CSS and layout inspectors
- file download analysis showing all HTTP requests and responses
In addition, it works on some versions of Opera Mobile which could be useful for phone developers. Finally, the widget is instantly updated whenever a new version is released; you won’t need to agree to a download, update or restart the browser.
If you’re viewing this page using Opera, you can try Dragonfly by choosing Tools > Advanced > Developer Tools. You can also install a debug menu for a little more convenience.
Dragonfly is a great tool and is likely to improve now more people are eying the code.
Do you use Dragonfly? What are your favorite features? Do you prefer it to Firebug, webkit’s inspector, or IE’s developer tools?
