So this wasn't added on purpose in bug 1476217 but I don't remember whether that was an oversight/misunderstanding or actually intended. I'll mark it up for triage.

I forgot to mention this, as a precondition: Content Blocking must be enabled (set browser.contentblocking.ui.enabled to true and restart the browser) if isn't already.

This wasn't an oversight on my part.  There was nothing in the UX spec that stated the behavior of this button is supposed to change.

Bryan, do you want the reset button to reset the DNT settings?  Either way, this is a followup.

Clear a needinfo that is pending on an inactive user.

Inactive users most likely will not respond; if the missing information is essential and cannot be collected another way, the bug maybe should be closed as INCOMPLETE.
