Steps to reproduce:

1. Launch FF3 (a fairly recent build)
2. In the location bar, type "javascript:alert('hello world')" and 
   press Return

Expected results:  Orca would announce the alert's title (JavaScript application) and then speak the contents (hello world)

Actual results:  Orca only announces the alert's title

If you look at the label for the "hello world" text in Accerciser, you will find that the label does not have a name (as one might expect *sigh*), but instead exposes the text through the text interface.  Perhaps we should be using getDisplayedText() instead.
