Turn off additional telemetry from Mozilla Firefox

For starters I wouldn’t co all the paranoic about Mozilla getting some telemetry as most of them are not about privacy. Some of you probably will want to disable those also this could help speed up Firefox a bit.

Get into internal settings by typing about:config in url bar and turn all of these to false by double clicking

I wouldn’t recommend you to do this on any non-stable channel release as those are heavy related with telemetry and making Firefox great.
