DOM Inspector

DOM Inspector is a tool that can be used to inspect and edit the live DOM of any web document or XUL application. The DOM hierarchy can be navigated using a two-paned window that allows for a variety of different views on the document and all nodes within. This screenshot shows a typical inspecting session.

Launching DOM Inspector

From within Mozilla

You will find it under the Tools > Web Development menu in any Mozilla window.

From the Mozilla sidebar

First you must install the sidebar, via Edit > Preferences > Advanced > DOM Inspector. After you have done that, simply open up the inspector panel and visit a website. It's that simple!
