Description Erik Arvidsson 2012-11-07 20:41:35 UTC 
It is unclear why we have TYPE_MISMATCH_ERR. In WebKit it is used in places where we have are supposed to throw a TypeError (which is often a violation of the WebIDL spec).
Comment 1 Jonas Sicking (Not reading bugmail) 2012-11-07 22:04:20 UTC 
I agree. We only use this in 5 places in gecko, all of which seems better to switch to throwing TypeError.
