Errors are collected via nsIConsoleService, shaped to a Sentry-compatible
format, and sent off. Reporting is on by default, and can be disabled using a
checkbox added to the privacy prefs in about:preferences.
Collected errors are sampled to avoid overloading the collection service; the
sample rate was determined by a previous Shield study that measured the number
of errors occurring in Nightly.
The feature is hard-disabled outside of Nightly and local builds, and the
preference is disabled by default in local builds. It is intended as a prototype
that will be evaluated and replaced by a more robust collection system if it
proves helpful.
