Sorry but you appear to have completely missed the point as to why Mozilla uses special math fonts, that the fonts with math characters in unicode position simply don't (yet) exist. STIX (and other projects) may change that situation one day, but not today. Your examples don't go much further than a+b and an integral sign: yes you can find those symbols in standard text fonts but that is hardly enough to cover the range of mathematics that one would need. Your screendumps show that your mozilla was incorrectly configured for mathml (no math fonts) so its unsurprising that it does not render mathml correctly. Incidentally in your discussion on the whatwg list you gave a long list of pointers to the mathml test suite and implied that they didn't work well in firefox. You didn't say what you thought was wrong, but all the ones I looked at looked OK in firefox, perhaps your problem was again just an incorrect local installation? It's absolutely no surprise that if you have fonts with the symbols that you need, and don't have any complicated requirements such as large brackets or subscripts on large base expressions that you can go a long way with css and/or css aided by a bit of javascript. For example there is my effort from 2001 (I think) http://www.dcarlisle.demon.co.uk/mathmlcss/ and others have done similar things, either using MathML markup to base the CSS or using a different markup. But in all cases while the result is "good enough" if you have very simple formulae, and your typesetting requirements are not too high, the mechanisms are really only useful as a fallback for cases where no mathematical rendering is possible.
