What specifically doesn't work? Do they not render (WebGL issue) or does your pointer not get locked (Pointer Lock issue)? Try googling "firefox pointer lock doesn't work", I'm sure something relevant will come up.

I'm not SafeSituation, but the demos don't render for me. Presumably that's a WebGL issue. (Google Chrome 23.0.1271.95 on Ubuntu 12.10)

Pointer Lock seems to work fine.
