well. few things to check without code. first make sure `this` references
your window global object, unclear on how you call hide and what it's bound
to. and that window.name is not undefined, unlikely to have been changed to
read only but you never know. then try to loop through `parent.frames[
win.name]` enumerable global properties to ensure mootools is actually
there and available. you are calling it on the other object directly rather
than reusing local one and passing a new context.
look through changelog for FF as well to see if any significant bugs or
issues have been addressed or what has been reported. also may
be applicable mootools version used.
