Cannot call an external file when running javascript in firefox

I’m trying to run this in my index.html :

<script>
var stockfish = new Worker('./js/stockfish.js');

stockfish.addEventListener('message', function (e) {
  console.log(e.data);
});
 
stockfish.postMessage('uci');
</script>

But I get the following error :
Security error: content located at file:///D:/ChessComparator/index.html cannot load data from file:///D:/ChessComparator/js/stockfish.js.
I cannot run web workers on chrome and I can’t think of another browser to test this on.
