Sorry for bothering the support team again but I have another question. After upgrading to Firefox v42.0 I have noticed a new folder in Appdata\Roaming\Mozilla\Firefox\Profiles\(profile name)\ saved-telemetry-pings. I was just wondering what is saved telemetry pings and I read it is feedback for Mozilla. Also I read you can disable it in Preferences-Data Choices which I have done but new files still get created in that folder.

Thanks in advance I hope this will be solved!
