Currently, JAWS does not support aria-hidden state in both Internet Explorer and Firefox.

You can use role="presentation" though it is not recommended.

Support for the aria-hidden attribute was added to JAWS in their 13.0.718 update (February 2012). See the full change log below:

JAWS now recognizes the aria-hidden attribute so that text that is supposed to be hidden is no longer announced.

It seems to work for me, but I've noticed that tabbable content wrapped in a "hidden" container can still be navigated to and read by JAWS.
