Have the same problem. Also on Firefox

Uncaught SyntaxError: await is only valid in async functions, async generators and modules

But additionally there are hundreds of warnings saying fetch failed:

Source map error: NetworkError when attempting to fetch resource.

Browser: Firefox-Developer-Edition

Same error as well but am running via Node.js

In order for this to work on firefox besides wrapping it on an async function like @azrogers points out is necessary to replace navigator.userAgentData (which it's not supported) with something like navigator.userAgent but for those who just want to run the script you can replace the line that starts with var ua = with:
var ua = "Mozilla/5.0 (X11; Linux x86_64; rv:121.1) Gecko/20100101 Firefox/121.1"; or whatever user-agent your browser has.

Unfortunately this doesn't fix it in FireFox 123.0.1 x64 Windows 10

Are you sure the problem is the user-agent string? Try changing the same line to: var ua = navigator.userAgent; it should work.

For me it worked using an IIFE, see here.

(async function main () {
    // Paste the entire code here
})();
