What steps will reproduce the problem? 1. Open http://webglsamples.googlecode.com/hg/aquarium/aquarium.html in Firefox 4 beta 2. Press "l" or "space" key

What is the expected output? What do you see instead? "l" should toggle lasers. "space" should change view. Nothing happens.

Keys do not work with Firefox since "event.keyCode" is used instead of "event.charCode". The solution would be to use "event.which" instead, since it's what jQuery recommends.
