Since Firefox 50 Emoji could be used inside a web page:
Firefox 50 release :" Added a built-in Emoji set for operating systems without native Emoji fonts (Windows 8.0 and lower and Linux) "

Step to reproduce:
1) Update Firefox to Firefox 50
2) Launch Firefox
3) Go to

Actual result: a lot Emoji are not here

Expected Result: All Emoji sould be shown

Workform: Manual install of the Emoji font:
1) Download
2) Extract EmojiOneMozilla.ttf
3) Copy EmojiOneMozilla.ttf in /usr/lib/firefox/fonts/ (badly it's no work in ~/.fonts/ )
4) Launch Firefox and go to
6) It's work!

Mozilla decide that Firefox MUST read Emoji and install a font for that for Windows et Linux's users. Badly, Ubuntu remove it.
For a better interoperability, Ubuntu should add EmojiOneMozilla.ttf
