LaTeX / KaTeX / math-jax doesn't render on many sites

Some math typesetting doesn't render. Neither on my desktop Firefox nor my android Firefox installs. I believe it is just KaTeX, especially from pages with github type markdown rendering.

This does not render correctly [image attached]. It appears to be a 'math-jax' typesetter actually, judging by the header scripts.

This does render... eventually. But the page layout jumps around. It displays the underlying tex for a bit before the typesetter executes. Very usable but a little jarring every time it loads.

The problem persists in safe-mode. I have also tried multiple extensions to force or add rendering support but none have helped.

That is a problem with blocked mixed active content as you can see in the Web Console with the MathJax.js being blocked. This works for me:

Okay, how to unblock in https?

To unblock this in https you would have to allow mixed active content (javascript files loaded via http) and this isn't recommended because this is a security risk and mixed active content is blocked by default for a reason.
If you have checked the Web Console then you should see that there is also a lot of mixed passive content like images loaded via http is present that isn't blocked by Firefox. This is a stronger indication that this website isn't designed to be opened via https.

You can contact the website and ask them to look at this mixed content issue.
