I use org-mode to write documents that are both exported into PDF via latex and HTML.
I use the package siunitx to typeset numbers with si-units. It is a bit tedious to do but I got used to it (unless I figure out how to make this work under org-mode).
When I export to HTML the things written in the siunitx-syntax are exported as plain text. I found out that org-mode uses MathJax for its HTML export. There is a third-party extensions for MathJax that is supposed to export siunitx syntax correctly to HTML.
How do I get org-mode to use this third party extension when exporting via HTML?
UPDATE:
Using the suggestion from @Nick I pasted the code into my user.el file. The code appears correctly in the org-html-mathjax-template variable. The HTML did not how the units correctly in a test file.
Looking at the HTML file, the script appears just before the </head>and beginning of the document in this form:
<script type="text/javascript" src="http://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS_HTML"></script>
<script type="text/javascript">

@Nick also suggested to check the developer mode in the browser (Chromium on OSX in my case). However, I have no idea what to look for.
**UPDATE:*
Since MathJax is not hosted on its normal cdn.mathjax.org siunitx and mchem are not working (in addition to accesibility-menu.js ??). I am not able to solve the issue but this is as for as I got:
(setq org-html-mathjax-template

Any idea how to get them running again? @Nick
