First, I am confused by the |font-variant-color| in the test case. I can't find any spec relate to this CSS property, not even in the latest editor's draft ( https://drafts.csswg.org/css-fonts/ ).

Besides that, I think this is a desired behavior change of bug 1231701. U+1F512 is a emoji-default character, to force the character black-and-white, you would need a VS15. 

That said, I can't get a black-and-white padlock with following test case on Mac Fx50, so we might have another bug here...

OS X only includes that glyph in the Apple Color Emoji font (The UnicodeChecker app is useful for that), there's no B&W variant for Firefox to use.

Right. The black and white version in my laptop comes from Source Code Pro, which aren't supposed to be used by Firefox unless explicitly specified anyway.

If there aren't second opinion, I would recommend closing this bug as WONTFIX.
