Orca and Firevox

[Hermann <steppenwolf2 onlinehome de>]

Hello,
I use Firefox 2.x together with the extension Firevox, which works 
pretty well, except one issue:
Firevox contains a function called "autoread", that means that, when 
pressing Control+Shift+A, the whole page gets read to you.
As speech I chose Orca.
I wrote to Charles Chen, the developer of Firevox, and I post my message 
and his answer here; after that I've some questions:

"I installed Ubuntu 6.10, Orca 2.17.90 and Firefox 2.0.0.1 on my machine.
The installed CLC-plugins work so far, with one exception:
I cannot perform the autoread function. The speech starts reading some 
words
but then Firefox gets stuck and the speech isn't talking anymore.
I have to restart Firefox in order to continue working.
Is this a known bug in Firefox under Linux?"

"A few questions before we go any further:

1. Have you tried doing this with Java FreeTTS?

If it works with FreeTTS, but not Orca, I would chalk it up to a problem 
 with Orca. I am dependent on the synthesis engine working properly, 
and  if the
synthesis engine suddenly stops accepting messages from me, there  is 
very little that I can do about it.

2. Did you set Orca to treat Firefox as a self voicing application?

If you haven't, Orca may be trying to fight Fire Vox for control; that 
is a really bad scenario, and strange things can happen."

Does anyone use Firevox either together with Orca or Free-TTS, and what 
is your experience?
How can I set up Orca, to treat Firefox as a selfvoicing application?
Regards
