According to this stack overflow, firefox now insists on using appendRule rather than insertRule, which would explain the "keyframe.insertRule is not a function" error I'm getting in Firefox. http://stackoverflow.com/questions/21460710/insertrule-and-addrule
Not sure why but this (as well as the original it is based on) does not work in the latest version of Firefox. Perhaps they've "upgraded" something.
