In case you're using Firefox on mobile - so myself and like four others - disabling Firefox' new Facebook data collection feature is quite a bit harder than on desktop, but it can be done:

  • Go to chrome://geckoview/content/config.xhtml
  • Use the search field to find the entry for aboutConfig and enable it
  • Go to about:config
  • Search for dom.private-attribution.submission.enabled and set it to false
  • Done. This only works on Android, because Firefox on iOS is just a Safari skin.

    @thomholwerda FYI, the first setting is under "general.aboutConfig.enable" on Firefox for Android. So search for "aboutConfig" not "about:config".
    @natarasee Whoops, totally right. Good catch, thank you! Fixed the post.

    @thomholwerda @natarasee ah, thanks very much for the clarification. I hadn't picked up that there were two separate toggles to check (my general one was already set to False).

    Now done 👍
