It seems as of recently the IBM Watson voices have stopped working. This has already been fixed for chrome, but when I tried to port the changes to Firefox, it didn't work.
I found another workaround for now, instead of changing the request origin header, simply don't send one at all. This can be done by going to about:config and changing network.http.sendOriginHeader to 0
EDIT: Something else broke and this workaround doesn't work anymore.
