The Performance tool in Firefox Developer Tools offers a great way to diagnose slow-running JavaScript and provides insight into the general responsiveness and layout performance of your web site.
In this video screencast, I’ll go through the process of how to diagnose issues with slow code and how to fix those issues in your code.
