How to disable Firefox Telemetry and Data Collection

+++

NFO:

Mozilla has provided few Settings on Options Page to select what kind of Data do you want to share with Mozilla and want to send to Mozilla Servers.

You can turn on/off Options such as Allow Firefox to send technical and interaction data to Mozilla, Allow Firefox to install and run studies and Allow Firefox to send Crash Reports to Mozilla Servers.

You can change these settings using Privacy & Security Section.

Even after you disable these Options, Firefox still collects and sends Data to Servers.

Open Firefox and type about:config in the Addressbar and press Enter. It'll show you a Warning Message, click on Accept the Risk and Continue Button
