Steps to reproduce:
I have a JavaScript code that recursively calculates time based on tempo changes. One file has around 2400 tempo changes and it crashes the tab.
I've narrowed the issue down to this basic example:
index.html
<!DOCTYPE html>
<html lang="en">
<body>
<button id="tester">Press to crash firefox</button>
<script>
document.getElementById("tester").onclick = async () => {
const context = new AudioContext();
await context.audioWorklet.addModule("worklet.js");
}
</script>
</body>
</html>
worklet.js:
function recursive(a)
{
if(a < 0) return 0;
return recursive(a - 1);
}
console.log(recursive(2400));
Actual results:
Gah! Your tab has just crashed. Tested on a Windows 10 64-bit Desktop and Laptop. With both stock firefox and the freshly installed Nightly version.
Chromium works fine.
Expected results:
It should work properly and return 0 like chromium, not crash the entire tab.

I couldnt get the testcase to work because of "CORS". Devs will be able to get it to work.
Tentatively moving to A/V.

Yes, I forgot to mention that the index.html has to be opened via a http server and not by double clicking, for example if you have node.js installed you can do:
npx http-Server -p 8000
And go to localhost:8000
