<p>wp-expurgate looks for HTTP links on your HTTPS site and converts them to HTTPS by running them through a proxy — so every connection between your site and your users is still encrypted.</p>

Run your blog on SSL? Tired of seeing mixed content warnings if someone posts a non-HTTPS image on your blog? Problem solved!

<p>This plugin adds the Modernizr to your WordPress installation.<br />
Modernizr is a small JavaScript library that detects the availability of native implementations for next-generation web technologies, i.e. features that stem from the HTML5 and CSS3 specifications. Many of these features are already implemented in at least one major browser (most of them in two or more), and what Modernizr does is, very simply, tell you whether the current browser has this feature natively implemented or not.</p>

Modernizr for WordPress

The 2.8.4 version inserts broken javascript link.  I posted a message about this in the support section for the plugin and the author has not responded or fixed the problem.  Now, any site that I've added this plugin to can be broken if the user runs an update.  

Instead, if you need Modernizr, insert the following into your header.php file just after <?php wp_head(); ?>:

<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/modernizr/2.8.3/modernizr.min.js"></script>
