Same here but after waiting a minute or so the spectrogram fills in with data and everything works. I think it needs time to download or process data? Firefox Quantum 57.0.1 on Ubuntu.

I must say although the technology behind it is way over my head this is one of the most impressive projects I have ever seen. Very well done and interesting indeed!

Sadly this appears as boxes with a blue background without spectrogram.
Is there something I can try?

Hopefully there was another message last night.

I think I've got the Hann window working now, it looks a lot
better and sharpens up the spectrogram quite nicely, eg
