spun off bug 617918 comment #1, original report:
JAWS does not read text message in new alert dialog in Firefox 4 and 5.
Frank asked to add this issue as additional information to this defect.
In Firefox 3.6, JAWS would read the text in the alert dialog. With Firefox 4 and 5, we have found two issues. First, focus is not placed on the dialog box. Actually, watching the events in AccProbe shows that the focus goes to the OK button but then goes back to the browser window.
If focus is placed on the OK button, we find that JAWS can read the OK button but does not read the text message. I tried both Insert + B and Ctrl +Home, Insert + Down Arrow.
Yes, for some reason we are no longer picking up the labels via aria-describedby in the new tab-based alert dialog. The markup is correct, though.

depends on bug 661293, actually could be a dupe.
a dupe, when the dialog exposes description_for relation then JAWS works fine
