I got
“KeyframeEffect is not defined”
That’s problem is known?
I can fix it with codepen page by add script for web-animation js.
Can this page be fix for animation run?

I don’t reproduce the issue.
Which Firefox version are you using ?

Also, are you talking about the “Firefox Developer Edition” animation ?

I got the problem . Need to use about:config to set the preference dom.animations-api.core.enabled to true.

We use HTML to tell stories and communicate vast amounts of information—and animation helps us do both better.

I’ve updated the sample now to no longer use APIs that are not shipping in release builds of Firefox/Chrome.
