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 I can't even open chrome://geckoview/content/config.xhtml - it just assumes I meant to enter an https:// address and f's it up

    @dtwx @thomholwerda If you paste it in, you have to manually add the prefix of `chrome://` again.

    At least in non-In Private Mode, that was necessary - it seemed to paste in fine in In Private Mode, though it... apparently kept those options around outside of In Private Mode based on checking in non-In Private Mode.

    @AT1ST @dtwx @thomholwerda the link doesn't go anywhere

    @NationMeta @dtwx @thomholwerda Huh - on Android Firefox?

    Should look like it goes to here:

    @AT1ST @dtwx @thomholwerda
    OP has extra letters at the end of the URL where there should be a space. I copied all of it without noticing. 🙂 Thanks for getting back to us.

    chrome://geckoview/content/config.xhtml

    @NationMeta @dtwx @thomholwerda Glad it worked out in the end - thanks for letting us know what caused the confusion!
