Details

I have a hypothesis: A significant portion of tab switch spinners occur for tabs that are newly created, and haven't ever shown their content before. This is because the content process is late getting the DocShell set up and a PresShell set up and painting before the parent gets impatient and shows the spinner. I want to gather Telemetry to see if this hypothesis has legs. If it turns out that first-seen tabs that show spinners tend to be "young" (perhaps less than a few seconds old), then we can probably get away with showing just blank instead of a spinner.
Merging this into the work that's happening in bug 1342464.
