Emoji Encoding

W7

That could easily be part of your problem. Perhaps Firefox has some kind of built-in emoji support while IE and Chrome rely on the OS for that. I don't think W7 has native emoji support like Win10 does. Does not seem like the sort of thing they would patch in shortly before the end of official support.

Windows — Windows 8 and 8.1

Internet Explorer — Yes!
Firefox — Yes!
Safari — Yes!
Chrome — No ☹
☹ If using Windows 7, Windows Vista, or any other early version of Windows, you will not see Emoji correctly in any browser.

And to finally nail the Firefox thing as well: https://www.mozilla.org/en-US/firefo.../releasenotes/

Added a built-in Emoji set for operating systems without native Emoji fonts (Windows 8.0 and lower and Linux)

So it's basically that your Windows does not support emojis, but Firefox has special built-in emoji support since version 50. That's why you only see them in Firefox and nowhere else.
