Firefox OS has its own icon font set available: this article explains how to use it in your own apps.
Notes
The Firefox OS Icon font can be downloaded from the Gaia icons store on Github, or you could use bower to install it:
$ bower install gaia-components/gaia-icons
Once you have linked to the gaia-icons.css file, you can use the data-icon attribute with one of the icon names you will find in the live reference example below, for example:
<div role="toolbar"> <button data-icon="messages">messages</button> <button data-icon="email">email</button> <button data-icon="call">call</button> </div>
Live reference example
The following gives you an idea of what the rendered icons look like, along with the data-icon attribute names you need for each one.
Code
Here is the code for the above live sample.
