The Signature Report in the Crash Stats website has a Correlations tab. When you click on that tab, it either shows you correlations for that product and release channel or it tells you there is no correlations data.
Correlations data is stored in files on another server outside of Socorro.
Correlations data is generated by code located at https://github.com/marco-c/crashcorrelations.
The correlations scripts are run in DataBricks.
Correlations are generated for Firefox using any fields that are in the
telemetry.socorro_crash data set in Telemetry.
Correlations are run on the top 200 signatures.
If you have problems with correlations, please write up an issue in their issue tracker.
See Telemetry (telemetry.socorro_crash) for adding fields to
