revisit 4602: dom.enable_resource_timing

[Thorin-Oakenpants]

Keep an eye on what gk does with this

https://trac.torproject.org/projects/tor/ticket/27268#comment:18

With RFP set, all of these timestamps will be clamped/jittered. Additionally, RFP has the behavior of setting dom.enable_performance to false (so you don't need to set that pref.)

However RFP does not have the same behavior for dom.enable_resource_timing - so you may want to disable that explicitly.

AFAICT I think he's wrong and dom.enable_resource_timing is fully covered by RFP.

According to this you always start a resource timing with some form of performance.getEntriesByType("resource") and that returns an empty array if either RFP is enabled or dom.enable_resource_timing is set to false.

Yes, RFP doesn't exactly have the behavior of disabling the pref like it does for dom.enable_performance but that's irrelevant because it instead hooks into getEntriesByType and returns an empty array instead of the list of resources available for timing.

I'd ping Tom but I forgot his GH handle, again ;)
Can you add him to the list of contributors or something so that his GH name comes up by typing @t ?
