Doesn't load in Safari

Safari- Shows "Loading Drums Sound Fonts..." with the blinking dot and stays there.
Firefox- Completely blank page
Works in Chrome

Thanks, for reporting, maybe you can see what developer console shows? Your OS probably is iOS?

Yellow errors are Safari, blue errors are Firefox. Firefox seems to have no other issues but css? Using Safari 12.1.2 and Firefox 44.0.2 with macOS Mojave 10.14.6 and iPhone Xr 13.3.1.

Update: Turns out my firefox was SUPER outdated. So it works now. But Safari is still broken
