Turning off the AI features in Mozilla Firefox

 In light of recent announcements from Mozilla towers I've been revisiting my choice of web browsers. For various reasons which I won't go into here neither Waterfox nor Librewolf were entirely satisfactory for me. Meanwhile here's the list of AI things to turn off in Firefox that I've found to date. Putting it here so that I can find it again and in case it's useful to anyone else.

How to turn off the AI features in Firefox

    In Firefox, type about:config in the address bar and hit Enter.

    Click "Accept the risk and continue" or similar wording.

    Search for each of the following options and change them all to "false":

  •         browser.ml.enable
  •         browser.ml.chat.enabled
  •         browser.ml.chat.page
  •         browser.ml.linkPreview.enabled
  •         browser.tabs.groups.smart.enabled
  •         browser.tabs.groups.smart.userEnabled
  •         extensions.ml.enabled
  •         sidebar.notification.badge.aichat


    Additional resources such as this additionally suggest setting these to False as well:

  •         browser.ml.chat.page.footerBadge
  •         browser.ml.chat.page.menuBadge
  •         browser.ml.chat.menu
  •         browser.ml.smartAssist.enabled
  •         browser.ml.pageAssist.enabled
  •         browser.ml.chat.sidebar
  •         browser.ml.chat.shortcuts
  •         browser.ml.chat.shortcuts.custom

        


This should disable most if not all of the embedded AI features. Note that not all of these will be set to True, some of these are not enabled by default - they may be False by default which is fine, meaning they aren't enabled.

These settings do not appear to sync using Mozilla Sync so need to be manually set on each of your machines that have Firefox installed.

This guide was current on 17/12/2025 but Mozilla may (for which read 'will') add more AI "features" in future releases.

The list above was found originally on this post on Ask Ubuntu
