  • P.S. Speaking of Firefox MathML, Neil Soiffer once mentioned in an e-mail "... support <semantics> (generated by MathType and other authoring tools) to the point of it not causing an error ... probably only a few hours work (just render the first child)." Perhaps he misspoke, but did Firefox do this, or maybe just render the last child?
