See bug 701758 comment 13.

I prepared new patches to fix this bug and sent them to the try server. For the moment, here is a patch for the website.

https://tbpl.mozilla.org/?tree=Try&rev=57febf443775 There are still issues with layout/reftests/bugs/355548-3.xml layout/reftests/bugs/355548-4.xml I don't know exactly which font-family value should apply here. The tests are the obsolete fontfamily attribute and the style attribute and I'm not sure how that all of this should interact.

A note here on CSS, deprecated attributes and mathvariant: http://www.w3.org/TR/MathML3/chapter3.html#3.2.2.1 But I think here the problem is the rule added on mi.

Odd that the user-agent rule is overriding the author style="font-family:monospace;" but only when the fontfamily attribute is present.

OK, Davide Cervone said that MathJax_Main is the same (more or less) as MathJax_Main italic. So I removed the rules on mi and that solves the problem of failing reftests.

And this patch is to use STIX/Asana Math/MathJax fonts on the demo pages.

(In reply to Frédéric Wang from comment #12) > Created attachment 604899 [details] [diff] [review] > patch - part 3 This patch fixes a CSS rule. I'm not really concerned about this rule not being applied for now, but that cause error messages in the CSS console and users are likely to complain.

Docs got updated on the MathML font article and a note has been added to Firefox 13 for developers: https://developer.mozilla.org/en/Firefox_13_for_developers#MathML https://developer.mozilla.org/en/Mozilla_MathML_Project/Fonts Marking this as completed then.
