[Affected platforms]:
- Windows 7 x64, 
- Windows 8.1 x32
- Windows 10 x64
- Mac OS 10.10
- Linux

[Steps to reproduce]:
1. Launch Firefox with a new profile and open the Browser Console (from menu [≡] → select "Developer" → select "Browser Console")
2. Navigate to .
3. Observe the Browser Console's content.

[Expected result]:

[Actual result]:
NS_ERROR_FAILURE: Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsITelemetry.getKeyedHistogramById] is displayed in the Browser Console.

[Additional notes]:
- Issue does not reproduce on Release (version 45.0.1, build id 20160315153207), Aurora (version 47.0a2, build id 20160406004015) and Beta (version 46.0b8, build id 20160404120533)
This is from PluginContent.jsm for the line:


PLUGIN_TINY_CONTENT is not a keyed histogram.

Regressed when initially added in bug 1237198, --> Tobias or François, can you take a look?

(setting affected to 47 as well because that bug *just* got uplifted)
Blocks: 1237198
Component: General → Plug-ins
Flags: needinfo?(tschneider)
Flags: needinfo?(francois)
Keywords: regression
Product: Firefox → Core
Also, .add(key) doesn't make sense. This is a count histogram, so .add(1) is the only value that makes sense.
Attached patch patchSplinter Review
Use getKeyedHistogramById(...).add(1) since PLUGIN_TINY_CONTENT is a count histogram.

Approval Request Comment
[Feature/regressing bug #]: bug 1237198
[User impact if declined]: Without this fix, we won't be able to collect plugin telemetry needed for our plugin blocking experiment (bug 1237198).
[Describe test coverage new/current, TreeHerder]: Just local testing. The patch landed in mozilla-central yesterday.
[Risks and why]: Low risk. This is a one-line patch that fixes how we report one particular telemetry probe.
[String/UUID change made/needed]: None.
