Hello,
Currently Firefox requires two additional headers being served when loading webassembly code:
Cross-Origin-Opener-Policy: same-origin Cross-Origin-Embedder-Policy: require-corp
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects...
These headers are soon going to be required in Chrome too:

Are they enabled in itch.io when serving HTML5 games? This is required when using webworkers, which are very useful for threading in games, like for Audio and other usages.
