The user that crashed reported vis our FirefoxNightly account that Firefox crashed while using Jaws 18 while having the developer bar (I am assuming he speaks about the devtools) open

fsdomnodefirefox.dll is on the stack of the crashing thread. Do you have any contacts that work on JAWS?
Pascal, could you ask the user if we can share the crash dump with the JAWS developers?
