(Oh, I should specify: This is Firefox for Android, both nightly and release, on an up-to-date Nexus 6P.
The examples at aframe.io don't work, with identical problems. The webvr-polyfill examples are 404ing right now. Interestingly, the aframe boilerplate example at https://ngokevin.github.io/aframe-react-boilerplate/ does work, on github, but doesn't work...
Is your gh-pages branch from dev, rather than master?
