This plugin adds an “Open In Social Debugger” link to the admin bar. The link opens the current page or post in Facebook Sharing Debugger.
This plugin works with pages and posts, and in both backend and frontend, as long as the admin bar is visible AND the page/post is in a published state.
<h3>Usage</h3>
On any page or post, in frontend or backend, you’ll see a “Open in Social Debugger” link in the admin bar, which opens the Facebook Sharing Debugger with the permalink of the current page/post for debugging.

This plugin is basically a wrapper for the excellent dBug (http://dbug.ospinto.com) class for PHP debugging, written by Kwaku Otchere..
Instead of var_dump or echo, you can call wp_dbug( $variable ) to get clear, dynamic debug output of strings, arrays, or objects.
Thanks to @borkweb, the plugin is now compatible with the WP Debug Bar plugin (https://wordpress.org/extend/plugins/debug-bar/) for extra debugging goodness!
