WordPress bloggers will sometimes copy headlines from a WordPress-generated homepage and paste them into the post-editing window. In Firefox, this has the unfortunate result of converting absolute urls into relative ones. For example, copying a headline from http://khaotica.com converts the permalink for this article:
http://khaotica.com/2009/12/firefox-relative-links-fix-wordpress.html
…to a relative link:
../2009/12/firefox-relative-links-fix-wordpress.html
This creates broken links when the post is viewed on the archive page and RSS feed. The links will also be broken for subscribers who receive posts via email.
Enter the Relative Links Fix. This plugin will replace relative urls with the proper absolute urls every time you save or publish a post. If you use WordPress and can’t shake those copy-paste habits, this is the plugin for you.
As always, donations are appreciated. I promise to spend them exclusively on soda (the creative fuel that powers developers everywhere).

Relative Links Fix

Corrects Firefox behavior in which pasting formatted content in the editor converts absolute URLs to relative URLs.

This plugin transforms any registered, enqueued CSS or JavaScript URLs into their “protocol-relative” equivalent.
Consider the following examples:
Protocol Relative CSS URL
<pre><code><link href="//example.com/wp-content/themes/twentytwelve/style.css" />
</code></pre>
Protocol Relative Javascript URL
<pre><code><script src="//example.com/wp-includes/js/jquery/jquery.js"></script>
</code></pre>
More appropriately called a “network-path reference” or “scheme-relative path”, a protocol-relative URL helps to avoid common scenarios such as:
<ul>
<li>Broken SSL padlock icon in browser’s address bar when showing mixed HTTP/HTTPS content</li>
<li>Error message in Internet Explorer saying, “This Page Contains Both Secure and Non-Secure Items”</li>
<li>Serving HTTP assets when viewing HTTPS pages</li>
</ul>
The idea of using protocol-relative URLs was popularized by <a href="http://paulirish.com/2010/the-protocol-relative-url/" rel="nofollow ugc">Paul Irish</a> and has become common as sites switch between serving HTTP and HTTPS assets.
This plugin will standardize all properly enqueued theme files to use protocol-relative paths, even those added from third-party plugins.
Note: This plugin does not transform any image paths that may be embedded in the WordPress editor or output as featured images or elsewhere in the theme — it presently only works on enqueued CSS/JavaScript files.

Protocol Relative Theme Assets

Transforms enqueued CSS and JavaScript theme URLs to use protocol-relative paths.
