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.

Simple Relative Urls plugin changes:
<ul>
<li>home and siteurl</li>
<li>script src urls</li>
<li>style link urls</li>
<li>images src urls</li>
</ul>
It uses wordpress filters. 
It doesn’t interact with database. 
It is fast, it doesn’t search and replace generated html. 
It doesn’t change hardcoded urls (for example in post content). 
It is flexible.
Plugin was originally created to enable wordpress to work with a <a href="https://www.npmjs.com/package/localtunnel" rel="nofollow ugc">localtunnel</a> npm package
<blockquote>
localtunnel exposes your localhost to the world for easy testing and sharing! No need to mess with DNS or deploy just to have others test out your changes.
</blockquote>
<h3>Example use cases</h3>
If Your development tasks don’t involve images, don’t download them from a server. Just install the plugin and add this line of code to your wp-config.php file
<pre><code>define( 'SRU_IMG_SRC_RELATIVE', false );
</code></pre>
Your local copy will then display images from their oryginal source.

Simple Relative Urls

This plugin makes urls (home url, js, css, images) across website relative. Works great with localtunnel npm package.
