After you have done a few other things within the application, you may have profiling code to supplement Firebug (a Firefox extension).

在应用程序中进行了其他一些操作之后，您可以获得能够补充Firebug (Firefox扩展)的配置代码。

Sadly, the current state of Firefox prevents Firebug from reaching the same level of performance, which is why I moved to Webkit from Firefox a few months ago.

可悲的是，Firefox的当前版本妨碍了Firebug达到同样的性能水平，因此几个月之前我从Firefox转移到了WebKit。
