hello! it doesn’t work in firefox because SharedArrayBuffer needs special steps to be enabled (see note 3 in https://caniuse.com/?search=SharedArrayBuffer )
Hi, Firefox has SharedArrayBuffer but not COEP credentialless by default. You can set this in about:config
just found out about this: https://itch.io/t/2025776/experimental-sharedarraybuffer-support
is the setting enabled for your game?
