NPAPI Plugin & IA2 accessibility Support - how can the plugin controls contribute to IA2?
We have an NPAPI Plugin which is embedding a Windows Application inside Firefox using the plugin container. The application we are embedding is being modified to support IA2 interface for it's various controls. When we embed this in IE (using BHO), it all works fine and JAWS works fine. But when we embed this in Firefox, as we hover over our application inside the FF tab, all we see is "Embedded Object", so basically FF is intercepting the messages and not letting the underlying window get hold of it and return appropriately. Even clicking inside out application doesn't help. Is there a way to tell Firefox that my add-on support IA2 so let it take care of it's own things?

If I understand this correctly, it looks like there is an API that is used to properly pass the DOM objects from the embedded application to the extension interface.

Hopefully this points you in the right direction, because of the platform access that NAPI plugins use it looks like this may be causing the issue? The MDN community and stackoverflow.com will have a better expertise on the subject as well.
