Hey, anyone know the name of the firefox plugin that will time how long your pages are taking to download? Ideally, I'd like to find one that helps me pinpoint which sections or files of a web site are the longest.

By the way, IETab is the business. I just discovered that you can right-click to set it to automatically open certain sites in the IE renderer in case they are chronic offenders. We have some internal development tools that fall into that category, so this is a godsend.
