Firefox: Disable feedback / heartbeat system

In Firefox 37 Mozilla implemented a feedback system called “heartbeat”, which should help to build a better browser.

Maybe you will be forced from this system or it may feel a bit flashy. Fortunately there is an easy possibility to disable the rating system in the about:config:

  • New tab > Enter about:config in your address bar and press enter.
  • Confirm the message “This might void your warranty!” with “I’ll be careful, I promise!”
  • Enter the following as filter:
    app.normandy.enabled
  • Double click on the entry to set it to false.

From now there should not popup any part of the “heartbeat” rating system again.
