Browser usage of CPOWs now fails. We should have telemetry to count these failures for the following reasons:

1) to make sure that when users have no addons, that we aren't seeing any CPOW rejections/failures
2) to correlate failures with addons installed to see if particular addons are triggering failures

mconley, do you know where I would add this?

Approval Request Comment
[Feature/regressing bug #]: bug 1233497 turned off unsafe CPOWs for browser code. This is telemetry to see whether that disablement is affecting users. I'd like this on all channels where we're turning e10s on by default.
[User impact if declined]: Less confidence in e10s working correctly.
[Describe test coverage new/current, TreeHerder]: I did basic manual testing before landing
[Risks and why]: I judge this as very low risk
[String/UUID change made/needed]: None

This should help give us useful data about e10s. Approved for uplift to aurora.
