new Date(1743623960000).toLocaleString(['en-ES'])

outputs "4/2/2025, 7:59:20 PM" in normal firefox and "2/4/2025, 7:59:20 PM" in Firefox Developer. Test on MacOS and Ubuntu.

new Date(1743623960000).toLocaleString(['en-ES']) outputs "4/2/2025, 7:59:20 PM" in normal firefox and "2/4/2025, 7:59:20 PM" in Firefox Developer. Test on MacOS and Ubuntu.

I don't think we understand 'en-ES'. It should be 'en-US' or 'es-ES'.

Thanks. Is there some web page where such different behaviours between Firefox Developer and Firefox is maintained ?
