I am seeing intermittent aborts of POST XMLHttpRequests in Firefox.

In FF DevTools Network the request line has a grey status circle & has no status number. The response tab is empty. In Firebug the status shows as aborted and I read somewhere this means the call was aborted by the browser (would mean server not an issue?).
  • Began about the time Firefox 46 became the production version (April 26).
  • Users do not experience these failures in Chrome.
  • Users are located around the world (not a local issue).
  • The requests being aborted seem to be random, occurs in less than 1% of requests.
  • No other request is active or made when the failure happens.
  • I have not noticed any GET failures.

Does anyone know of any differences between Chrome & Firefox handling of XMLHttpRequests that could cause something like this?

Looks like this is a bug introduced in Firefox 46.
Should be fixed in version 47 being released on June 7th
