This project uses PHP's gethostbyname() to show end users the IP address of their current web page.

1. Install extension from Firefox Add-ons site, or download the latest release and drag and drop the xpi file on Firefox
2. Browse to any webpage on the internet, and click the new "IP" button the top right
3. Enjoy!

To manually build the extension bundle (.xpi) from the source you need to install the Firefox Add-on SDK. Then execute the command jpm xpi from the add-on’s directory:

jpm xpi

This command will produce a file named ip-check.xpi. You can simply drag and drop it on Firefox to install the Add-on.
