Review for Emoji Menu by Ssurgul
Rated 4 out of 5 stars
Allows you to insert all the current emoji you want to annoy your friends with. :) Unfortunately, only handles black and white emoji, rather than allowing color. Hoping that will be enabled sooner than later.
This review is for a previous version of the add-on (1.1).To create your own collections, you must have a Mozilla Add-ons account.
