ES2015 modules in Workers are currently implemented in chromium only.
For other browsers you have to use importScripts().

You create a worker like this:

new Worker("worker.js", { type: "module" });

See: https://html.spec.whatwg.org/#module-worker-example

These are the bug-reports for each browser (please vote!):

• Firefox: Priority: Not set
• Chromium Browsers:
  Dedicated Workers: Available since version 80
  Shared Workers: Available since version 83
  Service Workers: prio 3
• Webkit: Priority: P2 Normal
