Thanks-- don't want to confound things by changing too much at once.
Let me go for a while not using the Turbomouse and see what that does... next time I freeze I'll try it.
But I don't see how a buggy Firefox add-on could possibly be allowed to take the whole system down. And not leave any trace in the console log.
