## Description

This plugin implements DNS prefetching per the Mozilla specification for the Firefox
browser. Hopefully, other browsers will eventually support DNS prefetching.

See https://developer.mozilla.org/en-US/docs/Controlling_DNS_prefetching for more
detail.

Disclaimer: This plugin is not affiliated with or endorsed by Mozilla.

## Installation

 1. Upload plugin file through the WordPress interface.
 2. Activate the plugin through the ‘Plugins’ menu in WordPress.
 3. Go to Settings » DNS Prefetch, configure plugin.
 4. View any of your pages, they should contain the following meta tag:

In addition, if you configured any additional domains, they should also be listed
after the line of code above.

## FAQ

  How do I use the plugin?

Go to Settings » DNS Prefetch and enter any domains you want to be prefetched by
Firefox browsers, in addition to the ones already linked on your home page. Make
sure the “enabled” checkbox is checked.

For example, you might have www.example.com linked on one of your subpages. By adding“//
www.example.com” you instruct browsers to resolve the DNS for that domain, decreasing
the latency should someone with a Firefox browser visit that page.

  I entered some text but don’t see anything on the page.

Are you caching your pages?

  I don’t want the admin CSS. How do I remove it?

Add this to your functions.php:

    ```
    remove_action('admin_head', 'insert_dpf_admin_css');
    ```
