Firefox requires cross-origin isolation to use SharedArrayBuffer. Here's how to fix it

1. Install the plugin Header Editor or a similar one that allows you to modify HTTP headers.
2. Download the JSON file below.
3. In the plugin config, go to "Import and Export" and select the JSON file.
4. Make sure to press save at the bottom.
5. Test out an app that requires SharedArrayBuffer.

🥳 It should work now.
Let me know if it does please. 🧡
