The Landmarks extension discussed in this post has been re-written to work on a range of browsers—please read our latest article on it for more information.
Landmark navigation is an increasingly important accessibility tool, and one that will become even more powerful as HTML5 is adopted, but it has mostly been restricted to users of “heavy” (and sometimes costly) assistive technologies (ATs) such as screen readers. Browsers do not offer keystrokes to move between landmarked regions on the page, so people who need to browse via the keyboard, but do not require the use of a screen reader, cannot benefit.
Introducing the Firefox landmark extension
Some time ago, David Todd created a Firefox extension that levels the playing-field somewhat, allowing users to navigate between landmarked regions easily via the keyboard. Recently I have updated this extension with support for the landmark roles implicit in certain HTML5 elements, such as
footer. Some of the elements only have implicit ARIA landmarks when they are labelled, or when they’re not contained within certain other elements. This is documented in the W3C HTML specification and is implemented by the updated extension.
The reworked Firefox Landmark extension can be downloaded and used right now. However, in re-working the extension’s preferences so they don’t require a Firefox restart for changes to take effect, I discovered that the current landmark position is not preserved across browser tabs. This means that currently you will lose your position when switching between tabs – but this is definitely something I plan to resolve in future versions.
Thanks very much to David Todd for his great work in creating this extension in the first place.

We hope it will be of use in improving keyboard access and, hopefully, convincing browser developers to include this functionality out-of-the-box.
