I think support for WebRTC is still only in Firefox Nightlies, not the stable version, or at least not full support.

I am on firefox nightly, and the website refuses to work. Looks like it does browser detection, not feature detection.

Same here. Pretty sure it's browser detection only.

I wish developers would honestly stop doing that already. Capabilities and stability are far more important than a logo.
