I am ATM optimizing a very old website and try to reduce mozAfterPaint events, to get an improved rendering result.
At the start there are so many events, you cannot count them. there are so many green lines inside the network graph that I cannot see if changes improve things or make it even worse.
it would be nice if the tooltip would show the number/count of mozAfterPaints events which occured, additionaly to the already shown timings.
