If you see typeset mathematics below, then MathJax is working. If you see
TeX code instead, MathJax is not working for you.
MathJax is not working!
WARNING: The browser you are using does not appear to support
MathJax, so we can't test if MathJax is working. Please try a different
browser, or a newer version of your browser in order to test MathJax.
WARNING: The browser you are using does not seem to support web-based
fonts, so we can't test the MathJax web fonts with this browser (image fonts
have been used instead). Please try a different browser, or a newer version
of your browser in order to test MathJax's web-based fonts.
WARNING: MathJax's web fonts don't seem to be available. Be sure you have
the MathJax/fonts directory in place before continuing.
If you fail to install these fonts, MathJax will not
work properly with some browsers. If you can't install the image fonts,
be sure to set the noImageFonts parameter in your MathJax configuration
(either MathJax/config/MathJax.js, or the
MathJax.Hub.Config() call in your web page).
WARNING: You are trying to load MathJax from a remote site where the
web-based fonts are not set up to be shipped to Firefox properly. See the
of Firefox's same-origin policy in the MathJax documentation for more
Once you have MathJax working properly, view the image mode test page to make sure that the
image fallback mode is working as well.
