Firefox: 404 on Your recent fiddles

[regeter]

I only see: 404 on Firefox for "Your recent fiddles"
No issues on Chrome. MacOS Firefox 136.0.1 (aarch64)

I have a specific Firefox issue right now.
When I click into any of these fiddles they still show the code but they do not show any result.

of note is that the 404 is actually an animation.

And? Issue still ongoing.

It's all links, all fiddles. There is also a URL in the screenshot.
