识别页面上实际使用了哪些外部javascript引用的工具

Question

I'm working on a website that currently has the same block of external JavaScript references on each page (added via a master page). I'd like to go through the site and identify which script files are actually necessary for each specific page to improve performance. Problem is there are a lot of pages and I'm not sure how to do it without resorting to manual trial and error process.

Is there a Firefox plug-in or some other tool that will identify which JavaScript references could actually be called by the page and which are not necessary?
