Wikipedia:Tools/Browser tools/Mozilla Firefox/Extension: Document Map

Description
 * Adds a sidebar (hidden when not activated) which shows a hierarchical list of headings on a page.

Installation

If a yellow bar appears under your toolbars:
 * 1) Browse to the Document Map extension page on Mozilla Add-ons
 * 2) Click the "Install now" link.
 * 1) Click the "Edit options" button on the yellow bar.
 * 2) In the box that pops up, click "allow" to let you install content from that site.
 * 3) Click the "Install now" link again to pop up an extension installation box.
 * 4) Wait a few moments until the "Install now" button becomes clickable, and click it to automatically install.
 * 5) The plugin will be installed the next time you start your browser (it must be closed to finished installing).

Usage
 * In Firefox, activate the sidebar through the menu bar (View >> Document Map). Click on a heading in the list to scroll to that heading on the page.
 * Caution: the default shortcut ([ALT+O]) to show and hide the Document Map is the same shortcut used by Wikipedia to log out. Pressing [ALT+O] with a Wikipedia page open will log you out, but have no effect on the Document Map.
 * You can install Keyconfig to change this shortcut (for example F12).
