"start ChatJax" installs MathJax and starts a loop that renders LaTeX as needed.

This is intended for use in chat, where the contents of the page are not static.

Reloading the page will stop the loop, so the bookmark needs to be run again.

"render MathJax" installs MathJax and renders LaTeX once per execution.

This is intended for use on web pages where the contents of the page are static.
