Summary: CSSOM Views specify offsetX/Y properties on MouseEvent. Other browsers implement them. Many sites use it with a fallback for Firefox, but I've found at least one site that doesn't have a fallback. It's trivial to implement.
Bug: https://bugzilla.mozilla.org/show_bug.cgi?id=69787 Spec: http://www.w3.org/TR/cssom-view/#dom-mouseevent-offsetx The spec has a few issues; I've posted to www-style about those, but I don't think they'll have much effect in the wild. Platform coverage: All Target release: Gecko 39 Preference behind which this will be implemented: I don't think this needs one. Other browsers already have this. There is a bit of risk due to sites taking a new path in Firefox, but I think it's low since this path is already taken in IE and Blink so they won't be checking offsetX/Y and switching on some Webkit-specific stuff, probably.
