Test browser plugin performance, memory leaks, page loads, etc

Question

We're having a series of browser plugins developed for us for Firefox, IE7/8/9, Chrome, and Safari, supported on Windows XP and up and on MAC OS X 10.5 and up. Are there tools out there that we can use to objectively test performance? For instance, how the plugins affect memory usage, CPU performance, page load time, etc?

Thanks SO!

Answer 1

For ie9 U can see load time for plugins in Manage add-ons, but I don't think that there is a universal plug-in testing program.

I will suggest You to use some programs from sysinternals suite to get advanced performance information's on windows platform.
