Quite amusingly:

site glitch doesn't work on the desktop FF too, not in any of three, with various staleness but nothing too old

works on the CodePen, but if I replace CSS there with the response of glitch.css from the Network tab - it blanks and never shows anything

no ad-blockers, no errors while loading

Thanks for checking, I’ll try to see what is going on.

Shoulda checked it in the first place:

    GET https://muffinman.io/js/posts/glitch/parser.js [HTTP/1.1 200 OK 138ms]

    Uncaught TypeError: animation is undefined
        parse https://muffinman.io/js/posts/glitch/parser.js:263

I've figured it out. The error means that this call fails:

    const animation = animationElement.getAnimations()[0];

As Firefox supports `getAnimations` since 2020, I figured something else is messing up with it. I've tried to enable "reduced motion" in the system settings and it broke the animation!

It is because I had force-disabled all animations on the site when this option is enabled.

I patched it, it should work now. Thank you for your help!

EDIT: typo

EDIT2: I also added simple error handling to display a message if parsing the animation fails.
