I looked at your sample with Accerciser's event monitoring.  What I 
would expect to see as I arrowed left and right among the characters in 
the generated text are object:text-caret-moved events.  What I'm 
actually seeing as I arrow left and right among the characters in the 
generated text is.... Nothing.

Orca expects to be notified when the caret moves.  Having received this 
notification, it then will announce the new location.  If Orca is not 
notified that the present location has changed, how is it to know that 
there's anything to update, anything to announce, etc.? :-(

While I haven't looked at this beyond what I wrote above, I would say 
Firefox.  My guess is that you didn't cause the lack of events.  But 
hypothetically, just for the sake of argument, let's say that you did. 
;-) I would still call what we are seeing a Firefox bug for failing to 
handle whatever it is that you hypothetically did. ;-)  In other words, 
visually I can see your sample application. Visually I can see the caret 
move from character to character.  Apparently Firefox has everything it 
needs to display what you have created.  We just need the information 
passed along to us so that we can present it to the user.

Hope this helps.  Take care.
