I'm not even going to pretend to know what's going on with this, or if it's even a 'bug'. I've attempted to use FF 6 twice and both times it has crashed, taking Photoshop along with it.
Using FF through the filters menu in PS CC 2015, I can cycle through filters within FF, but clicking back over to PS to view the original image and clicking back over to FF crashes both programs immediately.
I don't know what any of it means, or if it is helpful, but the info generated by the bug reporting tool is attached.
ON EDIT: I don't see the attachment..here is the text:
