I don't see the code that's recording these histograms. Am I missing something?

For all of these descriptions, please mention when the value is logged. Is it
every time the tool is run? Is it on start up of the browser? etc.

Ugh, is there a reason you named the histogram thus? Maybe it's not too late to
