I'm seeing a lot of this in the console when running a local build of Nightly: [Parent 2111] WARNING: 'NS_FAILED(rv)', file /home/keeler/mozilla-unified/toolkit/components/telemetry/TelemetryHistogram.cpp, line 2284 STR seems to be run Nightly, visit an https page, open the page info dialog, close Nightly (not sure if any of these are necessary except the first one...) The failing code in question appears to be: nsresult rv = internal_GetHistogramEnumId(h->histogram_name().c_str(), &id); I printed out h->histogram_name().c_str() to see if it was the same thing each time or something different, and there doesn't seem to be much of a pattern: DOM_SCRIPT_SRC_ENCODING#UTF-8 MAIN_THREAD_RUNNABLE_MS#Anonymous_interface_timer MAIN_THREAD_RUNNABLE_MS#Empty_microtask_runnable ... sub#A11Y_INSTANTIATED_FLAG#content sub#A11Y_ISIMPLEDOM_USAGE_FLAG ... sub#XUL_CACHE_DISABLED sub#XUL_CACHE_DISABLED#content etc.
Weird. I don't suppose you have telemetry turned on for this build? (MOZ_TELEMETRY_REPORTING=1, or the FHR checkbox ticked on in your settings...)
about:telemetry says FHR is enabled but extended telemetry is disabled. I didn't specifically set MOZ_TELEMETRY_REPORTING=1, so it's whatever the default is. Also, I can reproduce in a fresh profile, so it isn't because I flipped any prefs.
This must have been bug 1120409, which was backed out. Please re-open if you still see this.
