The PerformanceStats tooling can help characterize the intervening time, but it doesn't know about input events being pushed/popped. Could we do something about that?

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.
