Firefox is using a special font for these emoji characters. It's employing a relatively new and otherwise rarely used feature of TrueType fonts: layered colorcolour glyphs. Other than that (i.e. having a special font with pre-coloredcoloured glyphs) these icons are ordinary Unicode characters.

Windows has native support for these coloured fonts only in versions 8.1 and onwards, thus Firefox installs EmojiOne privately and uses its own font renderer for it in Windows 7. This also explains the absence of colourful emoji icons in most other applications.
