EmojiOne Color font doesn't replace black and white emoji font in Firefox or Chrome
I just tackled this on my machine (running 16.04). I don't like that I had to do this since Firefox 50 suppose to have native emoji support for operating systems that do not have them.
- Download the latest version do you desired location (I did to my Downloads folder) https://github.com/eosrei/emojione-color-font/releases/download/v1.3/EmojiOneColor-SVGinOT-Linux-1.3.tar.gz
- Uncompress the file (I use build in zip archiver/unarchiver
- Run the install.sh file found once you extract the EmojiOneColor with root privileges via terminal (sudo ./install.sh)
Then test with http://eosrei.github.io/emojione-color-font/full-demo.html
The other answer suggests to use EmojiOne, but it has reached its end of life in March 2018. Now rather have a look at its successor: the Twitter Emoji font by the same GitHub user. There are also user repositories (called PPA in Ubuntu) provided for Ubuntu, Arch and Gentoo. Using these instead of a manual install will update the font with your regular updates.
To install the font in Ubuntu I followed their instructions:
- Add the PPA with
sudo apt-add-repository ppa:eosrei/fonts
- Update the package index with
sudo apt update
(should be done automatically when adding the repository) - Install TwitterEmoji font with
sudo apt install fonts-twemoji-svginot
Afterwards you have to restart Thunderbird / Firefox to show the emojis in color.
