Fetch API cannot load file

Hi,

I get this error when running the code:

scripts.js:6 Fetch API cannot load file:///path/to/my/dir/wasm/sampelProject/squarer.wasm. URL scheme must be "http" or "https" for CORS request.

Hi, you can use https://github.com/kzahel/web-server-chrome and chose a folder for your project. This extension starts a web server and creates a link local project.

@Gaserd Is there an equivalent for Firefox?

This issue still persists in Chrome at 2022.
