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 bigger wtf is they hid about:config on mobile?? i remember just being able to go to it..
    @zvava @thomholwerda it's enabled by default on beta/nightly but not on release for some reason
