Strangely, of all the browser extensions I miss the most, the ability to display all embedded URL anchors is one that I thought wouldn't be important.

<ul>
<li>everywhere
    <ul>
    <li><a href="http://www.sensefulsolutions.com/2009/12/show-anchors-bookmarklet.html">bookmarklet</a>
    </ul>
<li><b>Firefox</b>
    <ul>
    <li><a href="http://chrispederick.com/work/web-developer/">Web Developer</a> &mdash; right click &gt; Web Developer &gt; Information &gt; Display Anchors
    </ul>
<li><b>Chrome</b>
    <ul>
    <li><a href="https://chrome.google.com/extensions/detail/bfbameneiokkgbdmiekhjnmfkcnldhhm">Web Developer</a> &mdash; available on Chrome too, woohoo!
    </ul>
</ul>
