Developers of rich, interactive applications like Facebook and Google Maps need to ensure that their masterpieces are accessible to all. The older tools are just not enough — they don’t understand JavaScript and dynamic, event-based page content. Deque’s next generation tools will help busy web developers find accessibility issues easily and fix them rapidly and establish the test scaffolding to ensure their application stays accessible.

A beta version of Deque’s Firefox/Firebug extension will be available soon. We will be previewing this at CSUN – March 22 – 27, 2010 (#CSUN10 on twitter). Register for the beta program.
