DOM Panel

Inside the DOM Panel you get information about all the different DOM properties and methods. For objects and arrays it offers a expandable tree view. Clicking on them limits the display of the DOM tree to these objects resp. arrays and shows the current element path as breadcrumb list inside the Panel Toolbar. Clicking on a function jumps to it inside the Script Panel. Note, that the panel shows a snapshot of the current state. Changes to properties don't take effect on the display of the DOM panel until you are refreshing it.

Options Menu

This menu is reachable via the little arrow in the panel tab ( File:OptionsMenuArrow.png ) or by right-clicking on on the panel tab (since Firebug 1.9).

Panel Toolbar

Property Path

The path from the currently selected property up to window is shown as breadcrumb list inside the Panel Toolbar. Clicking on one of the items displays the contents of the appropriate property of the DOM tree. Right-clicking on the Panel Toolbar offers an option for refreshing the displayed data.

Context Menu

Option Context Shortcut Description
Copy Name Property List - Copies the name of the selected property to the clipboard
Copy Path Property List - Copies the property path up to the selected property to the clipboard
Edit Property... Property List - Lets you edit the value of the property
Delete Property Property List (user-defined properties and functions) - Deletes the property
Break On Property Change Property List (user-defined properties and functions) - Script execution will be stopped, if the selected property is changed
Refresh Property List, Property Path - Refreshes the display of the Property List

Depending on the property value there are different options offered related to it. E.g. if the value is an HTML node, you'll be offered special options related to it, which are described inside the HTML Panel.

For functions the additional context menu options are:

Option Shortcut Description
Log Calls to "<function name>" - Logs calls to the given function; see monitor for more info
Copy Function - Copies the whole function to the clipboard

Color Codes

Different color codes let you distinguish between the different types of variables and improve readability. Here they are in detail:

Format Description
Bold Black Objects
Black DOM objects
get in gray "Getter" functions
Bold green User functions
Green DOM functions
Bold Red Constructor functions


Like in the Console, CSS and HTML Panel variables are auto-completed while typing. This enhances productivity and supports you making changes.


Note that localStorage is just an object so you can create, view, and edit it in the DOM view.
