About Firefox OS Emoji
Firefox OS Emoji is an open-source SVG icon set with 1,034 icons created by Mozilla. Every icon is free to use under the Apache 2.0 license — fine for personal projects, side projects, and most commercial work. Always check the upstream license for edge cases.
How to use Firefox OS Emoji icons
The fastest way is to embed an icon as an <img> from the Iconify CDN — no install, no build step, no JavaScript required.
Inline HTML
<img src="https://api.iconify.design/fxemoji/foxweary.svg" width="24" height="24" alt="foxweary icon" />
CSS background
.icon-foxweary {
background: url('https://api.iconify.design/fxemoji/foxweary.svg') center / contain no-repeat;
width: 24px;
height: 24px;
}React (with @iconify/react)
import { Icon } from '@iconify/react';
<Icon icon="fxemoji:foxweary" width="24" />Recolouring Firefox OS Emoji icons
Firefox OS Emoji ships with baked-in colours, so the icons keep their original palette wherever you embed them. Treat them like brand assets — use them as-is and avoid overriding the fill.
Search engine–safe usage
Always include a meaningful alt attribute on <img> tags or an aria-label on inline SVGs. For purely decorative icons (where text already conveys the meaning), use alt="" so screen readers skip them.
License & attribution
Firefox OS Emoji is distributed under the Apache 2.0 license. Read the full terms at the official license page. Most permissive licenses (MIT, Apache 2.0, CC0) don’t require attribution in shipped binaries, but it’s considered good practice to credit the icon set in your project’s docs or about page.
