Adds dns prefetching meta tags to your site.
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.

If this plugin breaks your site or just flat out does not work, create a thread in the Support forum with a description of the issue. Make sure you are using the latest version of WordPress and the plugin before reporting issues, to be sure that the issue is with the current version and not with an older version where the issue may have already been fixed.
Please do not use the Reviews section to report issues or request new features.
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.
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.
