Bill, informed sources tell me that you're the person to talk to.

To clarify, I pointed Yoric to billm since he wrote the e10s hang detector.

I think it should be pretty easy to add some counters that monitor how much time we spend doing sync calls into plugins. That's the only time I know of that plugins jank us.

We might also want to measure CPU usage of the plugin process. That by itself doesn't cause jank, though, so it seems less important.

about:performance is being redesigned; mass closing the bugs related to parts of the current about:performance page that we are not keeping.

Our goals with the redesign are to reduce the overhead caused by having the page opened, increase the reliability of the displayed information, and make the offered information actionable for most users. The back-end work is being tracked in bug 1419681.
