How to solve different FPS in `requestAnimationFrame` on different browsers?  

I am making a 3D game using `THREE.js` that uses `requestAnimationFrame` and it is fast on *Google Chrome 15*.  

However, it is really slow on *Firefox 6* and really really slow (slower than Firefox) on *IE9*.  

This is really a **big** problem and I am wondering if there is a solution to that.

Thanks.
