Official Description

From the Developer


Generates a navigable page outline with heading and sectioning elements

This extension is using the HTML5 outline algorithm to create a table of contents. Should also work well with HTML4 (and older?) pages, that have structured headings. The table of contents is clickable and tries to highlight the heading/section in question after the jump.

The extension should prove useful to people who find themselves often using online HTML5 outliners.
