RFE: Make a MathML font XPI which installs the MathML fonts and adds them to the Xserver's font path on demand.
rbs: I can create such a beast if there is interest in it...
-> Yeah, feel free to have a go. Re-assigning to yourself, and marking a dependency with bug 86247.
I don't know the extension system in details, but I'll see what I can do.
I have written an XPI with MathML fonts (STIX, Asana, MathJax) here: https://github.com/fred-wang/Mathzilla/raw/master/xpi/mathml-fonts.xpi It relies on downloadable fonts so can not be used for stretchy operators yet (see 663740 comment 8). It works with normal mathematical text, though.
Here is the first version of the add-on (not reviewed yet): https://addons.mozilla.org/en-US/firefox/addon/mathml-fonts/ I also opened bug 736010.
