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 going to chrome: surprised me
    @edzob @thomholwerda same. is android Firefox a chrome reskin?
    @joshg @edzob @thomholwerda no :)
    Before chrome was even born, Mozilla called the browser's interface "chrome" to distinguish it from the engine (gecko).
    I think that's where Google took the name when they built their "chrome" around khtml.

    @alex_pk @joshg @thomholwerda thanks!
    never knew that. today I learned 😊
