Mozilla implemented a method-JIT (compile whole methods) on top of their tracing JIT because a tracing JIT only optimises part of your code (only in loops and only if executed more times than the threshold) and there are further performance improvements to be had. So tracing JITs are not the *whole* of the state of the art.

May you do good and not evil
May you find forgiveness for yourself and forgive others
May you share freely, never taking more than you give.
