How to Disable Telemetry and Data Collection in Firefox

In our earlier post on managing Windows Telemetry and Data Collection settings, we have seen how to configure and turn off or disable Windows Telemetry & Data Collection for the entire system or individual components on Windows 11/10. The same applies to Firefox, but the procedure is somewhat different. Firefox , which claims to be over twice as fast as its earlier iterations, allow disabling telemetry and data collection.

How to Disable Firefox Telemetry and Data Collection

The browser ships with certain privacy changes and improvements that can be readily accessed via the Preferences page. These settings let the browser control the kind of data it would like to share with Mozilla and send to Mozilla servers.

Launch Firefox, choose ‘Menu’ (3 dots) and select Options. After that, access ‘Privacy & Security’ section on ‘Preferences’ page. Here, you can choose to allow Firefox to send technical and interaction data, and among others. However, even after configuring these options, Firefox continues to collect and sends data to servers.

To completely disable telemetry and data collection in Mozilla Firefox, do the following

Type ‘about: config’ in the address bar and press Enter. When prompted with a warning message, ignore it and proceed. Then click on the “I accept the risk!” button.

Now, type telemetry in Search filter box and look for following preferences in the result:

browser.newtabpage.activity-stream.feeds.telemetry

browser.newtabpage.activity-stream.telemetry

browser.ping-centre.telemetry

toolkit.telemetry.archive.enabled

toolkit.telemetry.bhrPing.enabled

toolkit.telemetry.enabled

toolkit.telemetry.firstShutdownPing.enabled

toolkit.telemetry.hybridContent.enabled

toolkit.telemetry.newProfilePing.enabled

toolkit.telemetry.reportingpolicy.firstRun

toolkit.telemetry.server

toolkit.telemetry.shutdownPingSender.enabled

toolkit.telemetry.unified

toolkit.telemetry.updatePing.enabled

Double-click on each above-mentioned preference except “toolkit.telemetry.server” and change their values to False. Alternatively, you can right-click on the preference and select Toggle option.

Now double-click on toolkit.telemetry.server preference and empty its value.

Once done, type experiments in Search filter box and look for the following preferences in the result

experiments.activeExperiment

experiments.enabled

experiments.supported

network.allow-experiments

Here, double-click on each preference mentioned above and change their values to False. Alternatively, you can right-click on the preference and select Toggle option.

That’s it!
