Chris, I think this is related to the recent bump to the mozilla-central version, could you please take a look?

browser.link.open_newwindow_restriction is expired. Recomponenting bug based on the expired metric.

I'm sorry, there were supposed to be emails sent which would warn of upcoming metrics failures but we don't yet have that capability. I'll be looking into fixing that presently.

bug 1744591 has a patch to remove the telemetry

Set release status flags based on info from the regressing bug 1740063

I think we can closed this as resolved fixed since the patch in Bug 1744591 landed and no recent failures have appeared.
