Comment:

 Firefox had a [https://bugzilla.mozilla.org/show_bug.cgi?id=1209480
 regression in FF41] related to rendering emoji in a `canvas` element,
 caused by an upgrade to their rendering engine. WordPress was affected by
 this, as it uses `canvas` to detect if the browser was able to render
 emoji or not.

 FF46 (currently in beta) fixes this bug. I just tested WordPress in FF43,
 45 and 47 - 43 and 45 use WordPress' emoji replacement script, 47
 correctly chooses to use the system emoji.
