title: Debugging the base URL element with Firebug
body: <p>I'm adding the <a href="http://reference.sitepoint.com/html/base" rel="nofollow noreferrer">base URL</a> tag to the document head using JS, so the relative links on the page work. But it does not take effect, and <a href="http://getfirebug.com/" rel="nofollow noreferrer">Firebug</a> (debugging addon for Firefox) shows the <code>&lt;BASE /&gt;</code> element greyed out.. why? Does this mean Firefox cannot understand it or the syntax is incorrect?</p>
