# [meta] MathML in MathJax

Not set

NEW

## Details

### (Keywords: meta)

MathJax is a popular Javascript library to display mathematical formulas in any browser. For Firefox, the native MathML rendering is used. MathJax is also able to convert LaTeX to MathML. However, our MathML support has some issues that prevent the markup generated by MathJax to render correctly. This makes some people switch to MathJax's layout engine and it's a shame.

This is a tracking bug for issues that have been reported by MathJax folks. It looks like more and more people are using MathML throughout this library and so it seems important to fix these bugs.

Printing issues reproducible using MathJax too?
MathJax using MathML-based rendering that is.
Depends on: mlabeledtr-support
MathJax also has its own Open Type fonts, which look closer to LaTeX fonts and thus are often preferred by MathJax users. That may be interesting to see if we can support them. They do not seem to contain an OpenType MATH table, though.

I've added dependencies to bug 697053 and bug 468568.

Things to do for MathJax fonts:
- horizontal braces (see bug 701758 comment 2)
- add rules in mathml.css (see bug 701758 comment 13)
- allow use of downloadable fonts (see bug 701758 comment 17)

I noticed that Firefox on snow leopard is extremely slow with MathJax content.

Stop and reload is helps but it's just strange why the page cannot load in the first request

This bug is to track MathML issues related to MathJax. Apparently, the page you refer to seems to use MathJax's HTML-CSS rendering so your problem would better be handled on the MathJax side or, if one can determine a precise reason of slowness in Firefox, as a dependency of bug 745687.

Anyway, MathJax's rendering engine is entirely written in Javascript and that's why it is so slow compared to the native rendering of browsers, especially for pages that contain a lot of formulas. Maybe MathJax's code can still be optimized (improvements have been made in version 2.0, but the page you mention still uses version 1.1) and Javascript execution in browsers can be made faster. But this will never be as efficient as Gecko's native rendering. So your problem will really be fixed by making MathJax use Firefox's MathML by default again, which is now the main goal of the present bug entry.

Other possible reasons:
- download time of Web fonts: to fix that, you can install local version of MathJax/STIX fonts on your system.
- LaTeX parsing: could be made faster if done before serving the page.

BTW, for those following this bug, Wikipedia now has an experimental MathJax option:
