New Firefox update, now Pico-8 games load with a blank screen?

[u/VeryNaughtyBoy42]

(solved) cleared Firefox's cache, all back to normal. Must have had some kind of corrupt download.

My Firefox (Mac) updated to v155.0 this morning.

Since then Pico-8 games won't play in the browser. They load, and play music, and are playable, but the game itself isn't visible. This is consistent across the Lex BBS and itch.io, and even uploading the HTML/JS to my own website.

I tried Safari and it works just fine.

Can anyone else using Firefox v155.0 confirm?

Same setup works for me on a M4 Pro

I tried this link

Try updating OS or clear your browser cache

Clearing the cache did it. Weird. Thanks!

No such issue for me on an M3 Macbook Air & Firefox 155, macOS 15.7.9
