Yes, I completely removed ~/.mozilla, it still does not work to edit
/usr/lib/python2.7/dist-packages/notebook/templates/notebook.html.
Maybe {{mathjax_url}} is not set and so that if statement is never entered?

Anyway, this worked for now, it seems. I will deploy this:

cd /usr/share/javascript/mathjax/config
mv TeX-AMS_HTML-full.js{,.orig}
ln -s TeX-AMS_CHTML-full.js tex-AIMS_HTML-full.js

so I get a symlink to use Common HTML instead of HTML-CSS:

root at muizenberg:/usr/share/javascript/mathjax/config#ls -l
TeX-AMS_HTML-full.js
lrwxrwxrwx 1 root root 21 Sep 20 12:16 TeX-AMS_HTML-full.js ->
TeX-AMS_CHTML-full.js

Regards,
Jan
